I’m having basically the same issue in that I moved my site to a new server (and hence a new IP address). Now the license won’t enable and my galleries are not being displayed.
You give them 5 stars – I give them 1, and would give them 0 if I could. Not a happy camper here.
Also, you say you’ve gotten good support – well it’s the weekend here now, so my site is messed up for the next 36 hours minimum. But I’m not so hopeful about their support as a previous support request I submitted was NEVER answered despite repeated attempts on my part to engage them. ??
