TeraCopy 1.22 Pro Portable Utorrent

I left a test of the files running overnight & it complete successully, but when I then tried to copy a different folder the machine immediately rebooted and when it came up teracopy was missing from the windows shell. I reinstalled 2 beta with same results then I uninstalled the 2 beta & installed 1.22 with the same results.
