Well actually it's not end of problems (when i fixed package, then maps lost connections with objects and in effect models and materials just doesn't show up), but when i installed older versionof UDK (January build, my old version) and open broken package then there were no problems.
Now i'm going to fix problems on january build and then move to april build. It should work.

Edit:
OK. Everything now looks to work properly on April build. Now i can continue working on this project
