PC Tuneup Disk Optimization Canceled

I have Norton Security Suite version 5.0.0.125 installed on my Windows 2008 R2 Enterprise Edition Server with SP1.  Every time I try to run the PC Tuneup Disk Optimization I receive the message PC Tuneup Disk Optimization Canceled almost immediately.  I do not have Windows Server 2008 Disk defragmenter setup to run as a scheduled task.  I can run the Windows 2008 disk defragmenter with no issue.  Is there a log file I can look at to see why it will not run?

I ran defrag from the command prompt with no issues.  I still receive the same error in Norton.
