I downloaded the newest version of Defraggler and attempted to run the program. I keep receiving a message from Windows stating a problem has been encountered, and Windows needs to close the program. This has happened 4 consecutive times as I've attempted to defrag my C drive. I was able to defrag my freesapce with no problem, and I've never had any problems with any of the previous versions of defraggler. The version I'm working with is 1.13.155. Any suggestions?
