Its not a question of paying for support, paul's answered the question here. The reason for going through support was so that the name of the site can be kept off the forums. Since you didn't give it initially it was thought that you didn't want to share it.
Send us an email at support at jamroom dot net. Not sure there's anything we can do if the site owners have chosen to block you, but if its just that they don't know how to un-block you then we can help with that.
include a link to this thread in the email along with detail on which site it is.
Sorry this is happening. I suspect its because we're mid way into developing the next major version and the repair.php script is looking for that stucture.
