The extension of the UIB file should be .uib not .bin.

Also, to decode it you have to specify where you want the definition and style file parts to go:

MPTools.exe /UIB=Decode /Src="C:\uibfile.uib" /Def="C:\deffile.txt" /Style="C:\stylefile.txt"

Can you show us the EXACT text you put into the command line?
