I donated and have been using this add-on for years, mostly w/o probs, and when I had probs, was easy to get help, quick responses from programmer. With new version, I actually donated again via paypal, followed all steps, have correct version, registered to my paypal email, but get flashing msgs, downloading, can't download, wait, wait, long error msg but disappears before i can read it. Have disabled all blockers, reinstalled sev times, made sure firefox up to date. nothing works, then i sent msg, got response they can't help, too many users, must email. but no email address is given. so basically now i've donated again, can't use the program any more and no way to get support. very unhappy.
