Hello yukon, I'm sorry you are having problems with MRU Blaster. Can you tell us which shortcuts were effected? Shortcuts from the Start menu, or perhaps those on the Desktop? I'll be moving this thread over to the dedicated MRU Blaster forum section where it will get the attention of the developer and other users of MRU Blaster.
There was one report of a similar problem back in July... But so far, the problem could not be recreated by Javacool. https://www.wilderssecurity.com/showthread.php?t=11063
