Mission Planner load error

Loading MP Windows tells me this" Unhandled exception:System.TypeInintializationException: The type initializer for "Mission Planner.Program’ threw an exception—> System.IO.FilenotFoundException:could not find or load file or assembly 'log4net.version= Culture+neutral PublicKeyToken=669e0ddf0bb1aa2a’or one of its dependencies. The System cannot find the file specified. Have already reloaded WinNET latest and tried Apache reload with no result. Any ideas? Thank you.

Solved.Just needed a hammer.
