Ghost 15 Live Update

I have Ghost 15 installed and running OK on a Win7 Ultimate 64bit machine.  When I try to run LiveUpdate I get the following error message:

 

  LU1818: LiveUpdate could not create a directory

  LiveUpdate could not create a directory that it needed

 

I have plenty of free space on all of my drives.  Plenty of memory.  All else working normally.

 

Any suggestions?
