BZ 1.4 works perfect in single player, online and over IPX. Red Odyssey works in Single player and I can get into the lobby just fine but when I create a game in Multiplayer (Online or IPX LAN) I get an Unhandled Exception.
I just now found the problem and fixed it! I will try to explain below:
I had a problem with RO not working because it could not find Battlezone. I have a dual boot system with Vista on the C: drive and WinXP on the D: drive.
First I had BZ 1.4 installed in (D:\Games\Battlezone) and RO couldn't find BZ so I installed BZ 1.4 in the default directory on the D: drive and RO still couldn't find BZ!!!

I then "Copied" the installed BZ files from the D: drive to the default install directory on the C: drive so when RO looks on the C: drive for BZ it will find it there. It worked!!
I could launch RO and it didn't give me the error that it couldn't find BZ. The only problem was that it would not let me create a game in Multiplayer.
The only thing I could think of that may be causing the problem is the fact that I "Copied" the install files from my D: Drive to the C: Drive instead of actually installing BZ on the C: Drive.
I removed the copied files from the C: Drive and actually installed BZ in Vista on my C: Drive so RO would be able to see the complete installed game instead of finding the copied files.
That did the trick! RO now works in Multiplayer just great!
I wish there was a way to tell RO where BZ is installed so I didn't have to go through all of this crap

Do you know of any way to edit RO so it will look for the installed BZ files somewhere besides (C:\Program Files\Activision\Battlezone)??
Hope you understood my lengthy explanation

If you have any questions just let me know.
Thanks again for your reply.
