Same problem here. I get an error message:
No entry 'IP_CMP_MERCS/IP_CMP_MERCS/description.ext/Campaign/Missions/Hub02.M01b

yep i get the exact same popup

Same it hapend to me too

really sucks too i was enjoying the mod up until that

Did you attack the local bandit hideout? I think that's what caused my problem. I restarted the campaign, avoided the bandits, played all the missions at the ION base, and everything is working fine at the British Knights base.

Same problem :(

Best you can do is: find the downloaded file (or download it from http://www.armaholic.com/page.php?id=25619) and put it in the folder "Campaigns" - if not excisting - create a new folder and name it Campaigns.
Worked for me and I can play it buuuuuut I've no idea what to do after the nice "conversation" with Miller and Stavrou at the very beginning - I just can't do anything what not will kill me :)
- Answer no - dead
- running around "there is a min...BAM - dead
- answer yes and go to the car Stavrou walks to, entering it, get driven away from Stavrou into a invisible minefield aaaaaaaand - Stavrou, Offroad and me - MIA (missing in action) and RIP (Rest in pieces) - gg
guess it's faulty or became faulty with the great updates from BI

Maybe somebody could tell me if he knows how to solve this problem or how/ if you can "survive" and play it or if you even have this problem (as well).
