Which assets is freezing? Does it stall while downloading the patch or installing?
Also, just to try something, please try moving the game folder to the desktop, run the setup file to "reinstall" there, and see if that gets any further.
Well....tried both of your suggestions, and now I am stuck at "downloading Main Assets 1". Should I just wipe the game off my system and reinstall it from my CD at this point and pray that somehow it works properly then? Getting rather tired of this not working.
