Bought Nebula a few years back and have used it without issues.
I recently had to re-install windows (7/64bit) and re-installed nebula along with my libraries, etc. I ran the plugin and the .ser file was in the c:/nebulatemprepository where it always is. I ran the nebula3license.exe file I received back when I bought the program and it seems to have done its thing without a hitch.
However, when I run the plug-in I get the init page with none of my libraries and the mast page of the plugin displays CUSTOMER at the REGISTERED line(see attached screenshots below).
Since I am using the same hard drive and have only changed my video card I figured it was OK to use the same license key file.
I would appreciate your help as I have a project to complete this weekend. I am using Steinberg Nuendo 5.
