I'm using Studio 2017. I translated a document this morning. Then I have a very similar document to translate and Studio is not filling out the segments with my previous translations. It's like everything I translated this morning did not get registered. When I hit F3, it doesn't suggest the translation I did this  morning. Tried rebooting to no avail. And when I do reboot, the "first use" screen comes up....? I've been using this version since it came out. And it erases all my settings and shortcuts and I have to redo them all. Any ideas?
