5) Hello! I have been a registered user of Convert Image for a while now, but recently had to do a full "erase and install" of OSX 10.2 due to some corrupted or incompatible applications (not yours). Now I only seem to have a demo version of Convert Image available. I'd like a fully functional version. Can you assist?

Mt registration schema is based on some infos related to your mac and some of these are based on your disk. So if You reformat, my app thinks is a different Mac!
Simply throw away prefs and run again my app.
It will ask a new code: click on send button as You did the first time. I will send back a new unlock key.
