"Warhammer cannot be run directly. Please run Warpatch.exe to patch and launch Warhammer."
So I run the Warpatch.exe and I get the error:
"the patch client was unable to retrieve the file
[patcher-goa.prod.sig] from the patch server.
please try the patch operation again in a short while"
I just wanna paly!

I have the game downloaded through Steam. Got the files all installed.
