MKKE .xxx files

[xenon90]

Hi
I'm trying to open some .xxx files from Mortal Kombat Komplete Edition, lets say a Character file. I've decompressed it, renamed it to .u and made sure the UE explorer was set to Console before opening. Here's what I get:

"Thrown by:LoadPackage
at UEExplorer.UI.Tabs.UC_PackageExplorer.LoadPackage()
at UEExplorer.UI.ProgramForm.LoadFile(String fileName)System.IO.EndOfStreamException: Unable to read beyond the end of the stream.
at System.IO.BinaryReader.FillBuffer(Int32 numBytes)
at System.IO.BinaryReader.ReadUInt32()
at UELib.UnrealPackage.Deserialize(UPackageStream stream)
at UELib.UnrealLoader.LoadPackage(String packagePath, FileAccess fileAccess)
at UEExplorer.UI.Tabs.UC_PackageExplorer.LoadPackage()
Unable to read beyond the end of the stream."

Which is a real darn shame since I've used this tool to mod an incoherent pile of mess that was Aliens Colonial Marines, and pretty extensively too. I thought MK was supported? Anyways, can't open any file so far from this game. Any help?

I've sent a report too...
