I have been using 4nt 5.0 for many years. It does what i need. So I've never had the need to upgrade. Over the years, I've move it several times as i have upgraded and changed computers. Most recently, I got a new laptop in October with Windows 7 on it. I installed 4nt, ran my reg key, and everything was fine. Then last week my harddrive crashed and I had to start over with a new harddrive. I installed 4nt as usual and ran the reg key as usual. But this time it keeps telling me I have the trial version. It does not list my name and serial number at the top of the command window when it opens. I checked the registry, and the appropriate reg key entry with the long hash string key is at the proper location in the registry. I've tried uninstalling and reinstalling several times. No change. The only thing different from when it was working a week ago and not working now is a new harddrive. Same Win 7 (64bit) same everything else. Any ideas what's wrong? Thanks.
