I tried to use wmp11 slipstreamer to integrate wmp11 to my xp cd, but since i'm danish and would like to slipstreame the danish version of wmp i got the following error message: WMP11Slipstreamer v0.90 System.ArgumentNullException: En buffer må ikke være null. Parameternavn: buffer ved System.IO.MemoryStream..ctor(Byte[] buffer, Boolean writable) ved System.IO.MemoryStream..ctor(Byte[] buffer) ved Epsilon.Win32.Resources.ResourceEditor.ReplaceMainIcon(Stream icoStream) ved WMP11Slipstreamer.Backend.CompressFiles() ved WMP11Slipstreamer.MainGUI.workerMethod(Object addonSettings) Deleting "F:\Temp\UXP\i386\wmp11temp"... FAILED! An exception occurred while attempting to delete the temporary folder to revert the changes done to the source.

Could anyone help me find a way to slipstreame the danish version of wmp??
