I’m fortunate in this case to have a Gmail account. Apparently only google emails are accepted, something about protecting us from the bad guys.
Before I could finish reading the screen about being patient, the license key email will arrive sometime before the 30-day trial expires… the email arrived. Program installed, registered, runs well. Program is from 2019, UI seems to be from 1996. Anyway, program seems very fast. Interface is confusing, I finally realized I could change the size of a filter (lower left corner) and that allowed combining the filter with original pic, otherwise you only get the filter. Some filters (like Textures) seem to ignore original pic altogether. Very limited set of filters in the program but I think it would be worth learning to use the filter editing capabilities. Seems like it would be much easier and faster than trying to find something good among 12000+ choices online.
