stuck at checking resources going on 5+ hours now..

What you could do is download the patch on another PC, copy the content.ggpk file over, and that should at least save you some time on checking resources - Sadly, there isn't much else that can be done! At the moment, the game resources are all in one easily re-patchable location, but that means the data all needs to have a roomy space to sit on your HDD.

That sounds like something in your pack file has become corrupted. Try running the Pack Check, which can be found at the top of the Support and Bug Reports forum.
