sorry, it's become very confusing
and you give us only part of information, it is very hard to help you

yes all flavor of 2.1.3 or even 2.1.4 Classic or Superserver, as you want

If you can't go back to 2.1, you can try 2.5 Superserver
but then, give us all the firebird.log if you have problem again
(you can use http://pastebin.com/ for that)
