I'm in exactly the same position...I have tried everything but cannot get MT/Language Weaver to work. I did however get an error:

After which Language Weaver was removed from the list of TMs and it now cannot be added.

I am pretty desperate now after wasting several hours with several deadlines looming... any help much appreciated!

I suggest you remove the plugin altogether and then reinstall it from the integrated appstore to make sure you have the latest version installed for 2021.

Also worth noting that you can get MT from Language Weaver without using the plugin at all:

Once signed in you will see this... just select Machine Translation:

Does that work for you?

Hi Paul,

Thanks ever so much for your advice but I'm afraid that I've already tried uninstalling the plug-in and reinstalling it from the integrated app store (twice in fact) but it made no difference. If I try opening Language Weaver via the method you've shown above, I simply get the following error message when I click on 'Cloud-based resources':

I don't suppose you have any other suggestions at all? Thanks! Amy

You could try working with the previous version of the plugin.  I'd make sure the old ones were completely removed first though, so close Studio and then delete these:

c:\Users\[USERNAME]\AppData\Roaming\SDL\SDL Trados Studio\16\Plugins\Packages\Language Weaver.sdlplugin

c:\Users\[USERNAME]\AppData\Roaming\SDL\SDL Trados Studio\16\Plugins\Unpacked\Language Weaver\

Then download version 4.2.18.3 from here:

 Archived Versions: Language Weaver 

Unzip it and install it.  Restart Studio.

I just went through this whole exercise myself and this works.  Looks like there is a problem with the new version of this plugin so I will change it on the appstore untl we fix it.  But for now please use this version from the wiki.

Woohoo! It worked! Thanks so so much for your help Paul!

Excellent... I have also replaced the one on the appstore too, so you won't get notifications to update it and anyone else looking for this won't have a problem.
