Have you tried contacting GT directly via their contact form or emailing Alex directly?
BTW: I know that GT is busy stabilizing GossamerMail and also working out bugs in LINKS SQL...I believe that after they address these app upgrades, they will return to DBMAN SQL and hopefully have a stable release soon.
I just got mail from GT, saying that DBSQL 2 has been released. It is not yet in the download area (for registered customers), it hope it only takes a few hours more to make it available online...
