hey guys, today i switched my steam from a HDD to an SSD and it made me reinstall all my games, i have all of the arma2's on my steam but when i went to reinstall the standard Arma 2 its size was only 5.2MB and of course because of this it gave an error that there was no entry to the .path... i was just wondering if anyone here knew of a solution to the problem? i have completely wiped my system of arma2 so i see no reason for this too happen... thanks in advance
