Help with CivIV

[Blitz_Fist]

I tried downloading the new patch online, in the game, but everytime it would just close on me after a few minutes. I downloaded it outside of the game, but when I installed it gave me an error "No valid source could be found for the game", so I press ok and it continues patching anyway and goes to the end and says it was successful. After this is done I go into the game and to internet multiplayer, and after I press login, it sits there for a second loading, then closes. I tried patching again, and it said I already have 1.52, but I did it anyway, and got the same results.

I'm using a no dvd setup (yes I own the game), and the mini image with sd4hider.
