I am a coder of a website http://striptalk.ru
We have your forum installed there http://www.striptalk.ru/forum/
It's version is old, we want to update it to the latest one. I don't want to update it by myself, I want to pay you to update it.
When I try to buy this option at your website, it asks me about license or an email connected to the license. But we don't remember anything of it - it was installed about 10 years ago, and the guy who has made it is out of the coverage now.
How can we do this?
