"The specified project location folder already contains some files. Please specify an empty or non-existing folder."

Question

Hi Community, 
 Some searching has confirmed that the above subject has already been addressed a few times. As far as I can see, the "solution" is to disinstall one version and install a previous one. However, the thread I encountered is 11 months old so maybe the bug has been sorted meanwhile? 
 Whether it has or not, my issue meanwhile is that I don't know which version of 2021 I have? This is how my license looks: 
 xxxxxxxx-xxxx-xxxx-xxxx-xxxxxxxxxxxx 
 Right or wrong version? What do I need to do? 
 The title error message used to pop up now and then. Lately it pops up ALL THE TIME and I am going gray over here 
 Thanks in advance!

Alessandra Cazzola You can find the version of your Studio by going to "Help - About Trados Studio": 
 The error message you get has nothing to do with the installation, it pops up when you create a project or open a project package and select a path for your project folder that already contains some files. Note that whenever you create a project, the folder for this project must be a new empty folder (as the error message clearly says!). 
 In case this message pops up already when you open Studio, I suggest you delete your list of projects by going to 'Documents - Studio 2021 - Projects" and rename or delete the file 'projects.xml'. After you restart Studio, the project list should be empty, and the error should not come up anymore.
