Defraggler locks up system

I have been using CCLeaner for a long time and I am a big fan.

I just downloaded Defraggler 1.06.118. I clicked on analyze and that was done in a few seconds. Then I clicked on defrag and the program started to work and then my entire system locked up in about two minutes. No error message. Control-Alt-Delete did not work. I restarted my system and tried again a few more times. Same result.

I am running Windows XP with Service Pack 3 on an Athlon 64 6400 CPU and ASUS Crosshair motherboard. I have 2 GB of DDR2 ram and am using a Nvidia geforce 8800 GTX video card. All of my Microsoft updates are complete.

I would try doing this and then posting the log back here.
