Yes, I see your license is a few months expired. I don't know what version you are running, but if you put in a ticket on this, we can send you what the latest version was at the time of your license expiring. Beyond that, you'll need a new license to get current versions.
The version I have is :
2.7.14d
and it was a pre release you sent me to solve huge SQL issue with previous version.
Problem is I didn't have this issue before (people could make purchases normally) until this version.
A member called us because he couldn't register.
Conclusion, we focused on this beta release because it was solving the big sql crashes issue (if you remember), without paying attention on other bugs that make registration impossible.
I am not sure paying for a new licence for this annoying bug is fair.
You shouldn't still be using that version. As I said, submit a ticket about it and we'll send you the latest version which was available during your license, which would actually be 2.7.17. That is more than fair to provide that. Anything beyond that will require a new license.
