I have the same problem will not activate after upgrading.
Why has this thread not been updated? Anyone come up with a solution can it be removed by ftp or is BH intent on reinstalling?
what was the resolution if you solved this? I have the same problem.
Right now it seems that if anyone is running Slideshow Gallery this is causing the error for mine.
I have this same problem the authors website is down for the slideshow has anyone got a fix?
