Help Installing map packs

[Grinix]

Alright so i think i got it done right but still me and my friend cant play these missions for some reason i say the problem is on his end but then again someone said that each pack needs to be in a different folder? i exracted all missions to one folder fwftestlabs or w/e the the 3rd pack had one additional folder and i took the fwftestlabs folder from that folder and placed it in the missions folder which then prompted to overwrite and i told it to go ahead and do so.

Here's a screenshot of what it looks like.
