I downloaded and tried the 15 day trial in June. I have now made some major network changes, and I want to see if ATI can do what I want / need it to do. I downloaded and attempted to do the 15 day trial again. Somehow, it knows I already did it once, and wont let me run it again. I uninstalled it, manually deleted everything in my Registry relating to Acronis, yet ATI trial still could detect a previous trial. What has it left on my PC that tells it not to let me do a demo again?
