GDIGuy

Well I found my 'The First Decade' discs and I was able to actually to play a bit of the GDI missions, (and as a side note the mod is AWESOME!) But now I cant get back into it and it always boots up ZH. Thoughts?

I either get that error message, or it will only open the vanilla ZH game. I think I am following all the directions but still no luck. I am running the game thru Origins. But I do have the old first decade game discs around somewhere if that would work better. Also to be honest this is the first Mod I have tried to download so I am totally lost with these kin of things. Any help would be greatly appreciated.
