Dear All

I pursued the upgrade from v2022 to v2024. It was declared I could use both versions. This reassured me that I wouldn't be completely out of action after the upgrade when something goes wrong. After the installation, when I tried to activate the new version, I assumed that I cannot use 2 ACTIVATED versions. I can keep the v2022 ONLY if I run the v2024 in trial mode. If I want to generate a license for v2024, I can only replace that of v2022 with this new license. So, then my v2022 probably loses its activation - I didn't dare to try - it stands in red, that this action is impossible to revert.
Actually, it would be OK, if the new version would at least work. In my case, after creating a new project I can't open files for translation, I get the error "Only docked panes may be pinned or unpinned". When I try to close the SW after this error, I get an error "Key not found: 'xxxxxxxx-xxxx-xxxx-xxxx-xxxxxxxxxxxx'. Parameter name: key". Moreover, all my TMs cannot be opened as well, the error is that they are corrupted, but they work with v2022.

No idea what that is. Neither in Knowledge Base, nor in Community, there is any information about it.
I started to use Trados from 'preTrados" version (5.5 or smth, 1999) and I don't see a need to buy a maintenance or support. I only have problems with installation and the biginning of usage of SDL Studio - since 2007.

My questions are:

1. If I upgrade the licence - will I still able to use activated version of 2022?

2. Can it be that the problem is that I used my saved user profile from an older version?

3. If I will not get help here - is there any possibility to get help from RWS only for this problem?

Thank you.
