you only need version 1.9 for it to work. ive experienced the same problem, but for me if i play more than 2 custom maps in a row, it seems to crash to my desktop. it probably just my comp, or the fact that i have about 40 custom maps installed all at once

anyways, to answer youre question, its nothing specific to the convo. pack, if you have the same problem i do, its probably just more noticable when you play the convo. pack cause theres more maps.
