jbbrwcky; (jabber wockey?) why do you seem so familiar??? Like most plugins (including WordPress itself) the plugin is free and we have free support forums. There are over 400 resolved threads in our forums though - so please don't be too quick to criticize ;)
Based on this thread I don't even know what you want. For a mere mortal to help you... well lets just say you need to provide us with more details :P
I was talking to Michael from All in One SEO and even he gets criticized for what often comes down user error. He also made the point that even Matt M himself gets criticized for either releasing WordPress Versions too quickly or not quickly enough. I have been observing the Next Gen Gallery threads and the same applies. It seems as though if you make something cool like WordPress, the All in One SEO plugin, WP e-Commerce, Next Gen Gallery... you are destined to be damned if you do and damned if you don't!!
Anyway. WP e-Commerce is our baby. We love it. We want to help. We always believe it is the putting right that counts. And providing people meet us half way we're even pretty flexible with providing free premium support (as long as it doesn't cut into our personal lives) :P
Ciao,
Dan
