Thanks for your help dude, so far what I did was install CMMOS 4.03+Axis rulesets+Allies rulesets+all GEM mods for Axis and Allies, and got them all up and working functionally, I can't seem to find the Semiotics and Darknight's 21st Army Group mods on CMHQ, but it's 11 PM over here so its probably just because I'm tired, I'll try looking again in the morning, thanks for your post dude, VERY helpful!!
My plan is to play through CMBO until I get tired of it, then move onto CMBB and finally CMKA, and inbetween that I have dug up my copies of the Close Combat series that I am also playing.
Anyway, huge thanks again for your help!
//Regards and happy holidays
