odbc recording and support by loadrunner 12

Hi,

I am using lr 12 win 7 trying to record an Odbc based application (due to protocol advisor). The application loads and than both loadrunner and AUT crush. The odbc version is 6.1. . What can be the cause?
I could record in delay mood skipping the AUT login.
I opened the firewall any to any.
I use admin user on client and server.

Advices?
Thanks
