I am another victim of the "operation terminated by user" error. I tried to to merge partitions on my RAID 0 array (the sole reason I boght this product) and everything went smooth, the PC rebooted and.... no changes. Tried 4 times with no success. Logs show that the operations were every time "termiated by user" in the reboot stage. And yes, I have the most recent build (#2117) for which I paid almost 50 bucks. And I also tried creating a boot cd but this version did not work with my mouse (another great feature). Unfortunately the tech support chose not to reply to my emails for almost a week and they do not even have a phone number to request a refund for this poor excuse for a software. It never happened to me with any other software I ever used. The acronis customer support sucks big time. They even have no FAQ for the current version of the Disk Director Suite on this forum (see sticky) and the so called "knowledge base" is lughable. Please respond. Otherwise I will be forced to contact my credit card company for refund of the charges for this useless software and try the competing product from Symantec.
