Some version 2 users have reported “lost” registration codes. They enter the code and their registration name shows up fine, only later to revert to “Registered to Customer preview”.
This is OK. The current version 2 is a “Customer Preview” which is active until July 4th. Registered or not, it then expires. Thus, when you enter a valid registration code, NoteFrog informs you of such by displaying the registration name. However, that registration information is displayed for that session only and the “Customer preview” registration is displayed upon restarting.
Version 2 will be released for download before the version 2 preview expires, so registered users will be able to download the formal version 2 release and continue to use version 2 features.
