Hmm. I'm sorry you're having trouble. I think it's having issues accessing information from our license file... unfortunately in a very unexpected way. We might have to do what it suggests - completely uninstall ProSeries.. but let's first see if we can confirm that.
Under the Help Menu, do you see a "Send Logs" entry? If so can you run that, then send the zip file it creates to email@example.com? That will collect a bunch of logs I can look at to pinpoint the specific error.
If you don't see that entry, can you update? It's something we just released Wednesday to help with troubleshooting in this community.
If for some reason you are unable to update, there are two main logs I'm looking for:
If you can find those directly, email them to firstname.lastname@example.org
If you don't want to mess with any of that, you can call into customer support and they can run through these same triage steps.
