I just downloaded your campaign and I love it so far!
Level 1 and 2 were just fine for me. But when I was like 3 minutes into level 3, the game gave me an error saying DKII stopped working and has to be closed.

I'm pretty new to this, so could you tell me how to fix this?

I am using the GOG version (1.7 i guess) and i used V0.27 of your maps.
Which version is the most used version of DK2? Why?

I am running a 64 bit windows 8.1 computer with an intel i7 2,4GhZ and a decent video card, so that shouldn't be the problem.

Thank you for your time!
