Ok ive got the same problem.. I cant connect to games in Zero Hour (It says that I have different version, I think my version is allready 1.04 standard.)
When I try to update Zero Hour I got the error: Old File not found. However, a file of the same name was found. No update done since file contents do not match.
I can connect in normal Generals.
I've got The First Decade version and it runs on Vista Ultimate 64 bit
So fat I set the Icon compatability options to run as XP SP2 and run as administrator.. I also have done a no cd patch and ive deleted
The INIZH.BIG file from the Command and Conquer Zerohour/Data/INI folder..
Does someone know any solution?
