Its your server; I'm not sure what is causing the issue, but it's not a bug with the registration system but it is an issue that needs to be worked through, likely through the Support Desk (Isaac and I are the 3rd party developers responsible for this product; official support goes through the Vendor through the Support System here who does not frequent these user to user forums).

I am a Web Development Contractor, I do not work for UBBCentral. I have provided free User to User Support since the beginning of these support forums.
