Problem with MCT

Hi all!
I get some problems with MCT...When I launch MCT an error message appears : "Error trying to install MidiPort DLL Library to: C:/Program Files/Java/Jre6/bin/" and it seems like my megadrum and Mct don't communicate each other.if I load settings from megadrum to MCT or viceversa, nothing changes...
what should I do to repair it?
