Hello, I activated by mistake NTFS for Mac (version 10 on Lion) with serial and password of a friend, not mine. Even after reinstalling it the old serial and password remain greyed out, I can't replace them. Thank you Mathieu
I remember going through an issue like this a year or two ago. I ended up having to uninstall, locate the file where the registration info was kept, deleting/renaming the file, then reinstall. Look under /Library/Application\ Support/Paragon\ Software, and try fooling around with some files there. HTH
