Checking DLC takes forever

I can’t play online multiplayer anymore since there’s always a timeout when checking for DLC. Problem occured today, before the patch was released. Earlier today I was able to play though. I restarted Xbox Live services manually and restarted my PC multiple times. I also checked my Toredo connection and it works fine. What else can I do? I haven’t tried to reinstall the game yet since that’d take a lot of time that I’d like to avoid.

EDIT: I gave in and reinstalled over the night. That fixed the issue.
