The thing is, some time ago I had the Ultr@ Pack installed (RC3 I think), and even though I properly uninstalled it and the game at that time, I think it may have left some files behind on the system drive or something, and these may be messing with my game. It's my only idea...

Nonsense!

You should look at your installation folder and delete everything there.
UP is certainly not installing any files anywhere on your system.

Basically you should have a stock game if you patch from 4.08m to 4.11 in the correct order, no matter if you uninstalled UP or not.

I suggest you download the Megapatch which is including 4.08m to 4.10.1m:
