Hey all, I just finished downloading all the required things, and installed all programs but when I click to join a server, i get a loading screen, (this goes quick) then another humvee screenshot type loading (also quick) but then I receive a recieving data bar which freezes consistantly on about 75%. This happens on every server and I cannot figure out why, anyways thanks for your help. Ps: When I join a game it says something along the lines that I have modified files, is this normal? or part of the problem? thanks

Hey Im really interested in playing this game, i just need to know for a 100% sureness that if I purchase combined operations on steam, rather than individually buying arma II and operation arrowhead, il still be able to play and enjoy this game. I'm sure this question is answered somewhere but i cant seem to find it, anyways thank you for your time and reply :)
