Hi there,
I installed Trados 2017 SR1 (last update) new because of several communication errors occuring while using groupshare.

I work on Windows 7 Pro 64 bit.

After the new installation, I get empty error message with a yellow "!" sign when I open a translation in editor which is using DeepL Translation Provider (in the project settings under Translation memory and automated translation).
I cannot work. The error message is popping up several times everytime I put the cursor in a line. The only option is to click ok. Then the empty message comes again.
If I remove DeepL from the project settings, the error doesn't occur anymore.

The log file shows these warnings:

Also, since I added the DeepL plugin to Trados, it has become impossible to add a comment in the editor.
If I do add a comment I get the error

reference not set to an instance of an object
when I try to save. It's impossible to save, only to click ok and the file stays unsaved. If I remove the comment, it's possible to save.

Do you have any idea what is going wrong?

I am aware it might be several problems. I don't understand what could be missing.

I already renamed the files in

c:\Users\USERNAME\AppData\Roaming\SDL\SDL Trados Studio\14.0.0.0\
e:\System\Dokumente\Studio 2017\

It did not solve the problems. Neither did the new installation.
