Hey WoofyWolf,
Yeah, that's not supposed to be happening. From what you've described it sounds like the game can't verify the integrity of the Database folders in the C drive location and is constantly in a state of installing itself. Kinda like steam has an update each and every time you start the game. If you'd like I'd love to have you submit a ticket for me and Lukas to run over. That would allow us to directly communicate and more speedily answer questions. You can submit a ticket at the link

Otherwise, I'd love to get some info about your game real fast.
What OS are you running on?
Did you buy the game through Steam/Origin/AppStore or directly from the OOTP Website?
Have you updated your game to the latest update, should be 19.13 Build 132?
Since it seems like a database location issue have you tried changing the database location to directly at the root of the C drive to see if that clears up the issue?
Let me know about the couple of questions above and if you do submit a ticket I'll be sure to jump on that with Lukas and figure out options for you.
Thanks
Alex
