VPK makes game crash

So, I've got custom camapign with custom models\textures\sounds. It works perfectly when not in VPK. But when I'm trying to test add-on in VPK, starting 1st map, it loads 20% then game crashes to desktop without error.
I think the problem is in custom models but it crashes only when in VPK! One time I've deleted all .sw .dx80 and .dx90 files from models folder and after that I've get 1st map loaded, but there was no models in it.

P.S. Campaign contains 5 maps, game crashing only when I'm trying to load map 1 and 2. Others are wokrs fine. And remember everything work perfectly when not in VPK.

Thank you so much guys, but I've found what was the problem.
