When opening a file in teamwork, the "sign in" window popped up. Nothing could be done with the file until I signed in. Once I tried to do that, I go the message "You are already signed in! If you abandon your current workspace, you will not be able to send any changes from your recent drafts." Since I couldn't do anything else, I signed in anyway, and it was right - I couldn't changes after that.
I was then told the file could not be found anymore, I had to find it manually. It would let me see the file, highlight it and choose it, but then it would act like I never did that, so after a few futile attempts, I gave up and closed the window. Also, all administrative information was lost at some point in this process.
Has anyone else encountered this problem? Any suggestions how to avoid it?
