I went through that with one of there image hosting sites, it seems they had like a melt down. My license stopped working, my membership vanished, emails to them bounced. I was able to fix it because someone gave me a older version of the software before they started using the license key junk. Its encoded into the software, and switching keys probably won't work. I switched mine and it worked for one night then had the same issue.
If you can find an older version of the script before they started using the license junk then you might be better off, thats how I got around it. Its was the same script but no license thing. I have send several emails to them but no response, ideally there system should come back up, but who knows how long that might be.
Thats another issue, I have talked to a few members and it seems everyone has lost their membership. Its like their database was lost. Which sucks cause I am sure some people lost more then the 2 months of membership I had left.
