Is Loadrunner 12.01 compatible with SiS 11.23?

Hi,

Is Loadrunner 12.01 compatible with SiS 11.23?  I am currently getting protocol errors when running a web script monitor.  I have been told to use an older version of LR (9.51 or older).  I have tried that (8.1) and I still get the protocol error.

Any advice would be appreciated.

Thanks!
