Sup, My first time on the forum.

So, To the matter at hand, Generals challenge will not start. I tried using Ironside, Townes and Tao, But the screen just went black and gone to 'Serious Error' BS.
This happens in Zero Hour as well.

NOTE: I don't have any other mods bar RotR in the root folder, I mainly use CrosuS.

If it happens with vZH, uninstall ZH, delete directory and reinstall, be sure oto patch to 1.4 unless you have the first decade.

Also, try installing to an alternate folder outside program files e.g. c:\games
