CoW 1.5 siege crash

i have started a campaign as Khorne and every time i attack the rebel dwarfs right beside my capital my game crashes on the loading screen. it says something like this: "unspecified error. Closing medieval 2". Before i attacked the rebel dwarfs i attacked some other rebel setlement and that one didn't crash.

i downloaded the torrent version of the mod because on the CoW developers site (the russian one) i have to pay to be able to download it fast,whitout having to download a lot of files that will take days.

NVM i reinstalled the mod with patch 005 and i seems to have fixed it. However now i get "Sigmar preserve us" CDT error
