Hosting mods on AlterIWnet

I need help with hosting mods on AlterIWnet.
I have read the tutorial and I did everything right, the mods are in the right place, but when I load a mod and start a match, it doesn't work. When I look into the folder of the mod that I'm loading there is a 'games_mp' text file. But when I restart the match my console floods me with "error: unknown gametype name". Does anybody know what could be the problem?

can you tell what mod were you using?

Never mind, got it working now. Turns out I had forgotten to tick the box to choose a ZIP format in stead of RAR format for all my IWD files.
