Hi Spyder,

LOL - no worries - I really do appreciate all the help...

Yep - CBA was installed via Steam and appears up to date - same obviously with Arma... Both RHS and IF updated too via their respective processes...

When I first noticed the issue - couple days ago - I had just started messing with Arma after an extended break - I noticed ALiVE was now available via STEAM so I installed it from there... Part of my troubleshooting last night - I completely deleted it from STEAM - went to your site and downloaded fresh copy and installed it the old way...

I'll post the mission tonight - maybe I've just been staring at the issue so long I'm missing the obvious...

Thanks one and all !

Regards,
Scott
