I installed the trial version of ATI on both of my computers and the trial eventually expired. I purchased two copies of ATI which arrived at my home yesterday. I ran the installer on one of the computers, it prompted me for the serial number which I entered. It then proceeded to "update" my existing installation. I launched ATI after it completed and was greeted by the alert that my 15-day trial had expired. I was given the option to "Buy Now" via the web or "Cancel" which quits the program. No option to enter my serial number. So..... I tried uninstalling the application and reinstalling it fresh. This time there was no prompt for serial number during the install. When I tried to launch ATI, I got the same message with the same options. I'm sure something was left behind in the registry to prevent people from doing infinite trials. However, whatever Acronis left behind seems to prevent me from upgrading to my fully-licensed versions. Can anybody point me at what I can do to make ATI accept my serial number? Thanks.
