Error message: Index was out of range?

Sorry for posting this on the older version forums by accident. I've downloaded the mod today on to my origin version of the game and it's not working. Every time I open the launcher it says Error message: "Index was out of range. Must be non-negative and less than the size of the collection."

Does anyone know what this means or why I'm having this problem? I've checked and it seems I have all the files required to launch the mod and my game is patched. Not sure what's happening.

You have to set the gamemd.exe to run in 16-bit color mode, and also as administrator, I think. Also possibly in WinXP SP2 compatibility mode. Probably the other base game exes too.

How do I run it in 16-bit color mode? I've changed the compatibility and run as administrators. Just unsure on the color mode.

I've tried everything you've suggested... tried to launch and still getting same error message. What else can I try?

Get the manual MO update, doesn't look like it's there because you still have the old splash screen.
