I have problem with mod. When I try to lunch skrimish mod I get error mesage an game crashes, this is in Zero Hour 1.2v In Generals i don't recive any new units.

Ok firstly what mod!? that whould usually help a lot, try uninstalling Zero Hour, deleting the ZH folder, then installing it again.

Well it's in the Real Threat forum so I presume it's the Real Threat mod... 😉

First, you should make sure you have the correct version of the mod. There's a version for Zero Hour and a version for Generals. (i.e. don't be trying to use the Generals version with Zero Hour or vice versa.)

Also, make sure you don't have any other mods installed while trying to use Real Threat.

What error message exactly are you getting when the game crashes?

If worst comes to worst, however, Jaymoiz's suggestions may be helpful to troubleshoot the problem.
