On my PC everything is working right, but on server I get this error:

System.IO.FileLoadException: Could not load file or assembly 'Ionic.Zip.Reduced, Version=, Culture=neutral, PublicKeyToken=edbe51ad942a3f5c' or one of its dependencies. The located assembly's manifest definition does not match the assembly reference. (Exception from HRESULT: 0x80131040)

I checked sources on the server - it's right version. What can it be?
