LoadRunner protocol for Sungard Banner SSB

Does anyone know what the appropriate protocol for the record/playback of Sungard's Banner SSB? I've tried many of the WEB/HTTP combinations with the different HTML-based script, URL-based script, and Web Click and Script. The recording seems to go fine as does playback in Vugen, but when I try to run 2 users in the controller, the application gives an error that says 'A break in attempt has been detected! Please login again'.

We have LoadRunner v9.51.

Thanks for your help!
