Hi Anja,

The most likely thing is that some external change, an update or moving files in Windows Explorer for example, has removed the list of projects from your Studio Projects View.

The projects are very unlikely to have disappeared. The work you've done is probably still in the TM you used, you've probably opened a different TM, for example a main TM instead of a project TM. Once you reopen your projects you'll be able to see which TM was ticked to Update. For example if you have a main TM and a project TM your work may have updated to the project TM but not the main TM. It depends on your settings.

If you go here in Windows Explorer (or via Open Project on the Studio Projects screen or the Welcome screen):

C:\Users\YourUserName\Documents\Studio 2017\Projects

you should find all your projects (unless you have deliberately saved them elsewhere).

From there left-click into the individual project file and double-click the project folder icon, such as highlighted here in blue:

The above is via Windows Explorer.

Here's how it'll look via Studio Project View (or Welcome view) via Open project:

This will open the project in Studio and should give you that project with everything that it was working to and with (so long as you haven't moved the relevant files or renamed a folder that is in the 'filepath' that Studio has saved to the project folder).

Repeat for any projects you need to access. You can do this at any time if you haven't finalized the project (I never finalize projects because I often refer back to them for example to re-open them as test projects).

I hope I haven't given you too much information at once and that this helps!

All the best

Alison
