I downloaded and installed the demo of ReelSmart Motion Blur. After being pleased with the results (blow away... actually), I purchased the software through the online store. I received my registration key via email, but I can't figure out how to enter my registration key and "authorize" the software. I saw a dialog box when I launched the plug-in the first time (in After Effects 7.0 on a Mac) and chose "use demo" since I did not yet have a registration key to enter. However, I don't know how to bring that dialog box back up so that I can enter the registration key that I now have.
I guess I'll try removing all traces of the plug-in and then re-installing. Is that the only way?
