Error code -6001

I did everything, i'm asking help, in agony.

Get rid of the patch, my Rome Total War always ran best in the vanilla version.

Does this error happen when you try to open the game or when you try to patch it? Search it online if it's a problem with either, and if it's just the patch try a different download mirror.
