Steamy Theatre of War 2: Africa is available!
 

You get both the original ToW2: Africa and its addon Centauro here.

Got the entire package !, 2 afrika + dlc and kursk.

Africa (first one i choose to start from) keep asking netframework everytime u start the game, and more it often crashes during loading.

Quite sad, because the game is awesome. :(

It also crashes during gameplay (total pc freeze, need restart) but i guess it's because my gpu (gtx 260) cannot stand full graphic options ay max detail.

Total pc freeze indicates overheating, power or drivers problems. Even if an application acts really wrong, it can't freeze a PC completely in normal circumstances (OS won't allow it). I suggest checking the cooling in your PC (CPU, GPU, motherboard) and stress-testing it. Unlike many other games that are mostly video-card dependent, ToW games use the CPU a lot, actually more than the video card, so i think that either CPU overheats or power supply drops voltage under heavy load in your case. And make sure your video card drivers are up-to-date, of course.
