My computer meets the requirements but it still wont run. (And again, no error message pops up after trying to run it which doesn't help me at all when I'm trying to figure out the problem.)

I already have diabdat.mpq copied into the folder.

Hi, I just recently downloaded this mod and I can't get it to start. When I try to get it to run, nothing happens. Not even an error message.
What's going on?
