HiVassily Buryanau 

Can you confirm that you are not using AnyTM for the server based TMs? Please see the instructions from the below article, and kindly let me know if works:

- Creating project/package/project TM fails with error message: Unexpected exception when initializing task 'Populate Project Translation Memories': Unable to cast object of type 'CompoundLanguageDirect - RWS Customer Support

Kind regards,

Hi Ana,

Answering your question, I've never used AnyTM for the server based TMs. To use a server based TM, I go to Project Settings -> Language Pairs -> Translation Memory and Automated Translation, then click the Use button, and then, in the list, click Server-based Translation Memory.

The instructions in the article mentioned above are not applicable to my situation, i.e., I don't use AnyTM, and I try to populate translation memories in existing projects that I've worked on multiple times before. Even though a part of the error message is the same (i.e., "Unexpected exception when initializing task 'Populate Project Translation Memories'"), the error seems to be different (please compare the error screenshot above and the one in the article). Also, please note that if I open the same project in Trados Studio 2019, project translation memories can be populated with no problem, and, after that, these project translation memories work fine in Trados Studio 2024.

I'd appreciate it if you could suggest other ways to resolve this problem.

Thank you,

Vassily

Do you have any MT configured in your project? And are all your TMs updated?

From what you write, I understand you having a single project, where you add and delete files? Try to remove all TMs from there, restart Studio and add the TMs again.

Based on my experience, it makes more sense to create new projects using a template instead of keeping one project and exchanging files there. Or at least creating a new project for the same purpose every now and then, maybe once a month or so.

Hi Jerzy,

Yes, I have one server based TM configured in the project, and it's been updated. And I've already tried removing the TM, restarting Trados Studio 2024, and adding the TM again - unfortunately, after that, the project translation memory still can't be populated. Also, I've tested populating translation memories using Trados Studio 2024 in a few projects, and it's failed every time with the same error message.

I didn't think about creating a new project instead of the current one because I don't have the same problem with any of my current projects if I open them in Trados Studio 2019, so I assumed that something is wrong with Trados Studio 2024, not with my projects. I'll give it a try later today.

Thank you for your advice,

Vassily

I understand. And I'm sorry, but I do not have experience with server TM and project TMs. Maybe the problem is the mixture of server and local TMs. But I cannot tell.

Creating project TMs is directly connected with the analysis task. Maybe the settings there can influence this process. Also make sure, that you have selected "optimised performance" in the batch task settings. These my only ideas here.

Well, turns out, I can't even create a project (please see the screenshot below)...

Thanks Vassily Buryanau 

I think the most likely problems here are related to a corrupt template, or an old one, being incompatible with the version of Studio you are using.  Might be worth checking if you are using a project template from an older version of Studio (which is a bad idea) or perhaps create a new project template just to test it again.

Or, another potential source of the issue is the path being used for the project, which the Project TM sits on.  If Studio doesn't have appropriate permissions to access that location this could also be a problem.  Maybe try setting the project path in your template to a location on your C: drive close to root and well away from OneDrive or any other possible interferences.... just for a test.

If neither of these things help I'll log a case so the tech support team can take a look.
