HELP with Optivity 10 Solaris

[NMSman]

I have installed Solaris 8, fully patched, HPOV 6.2 patched and then Oracle and Optivity as described in the manual. However upon trying to start any Optivity application, either via HPOV or from command line, i get the following error. Anyone come across this one before ? I'm stumped..

An unexpected exception has been detected in native code outside the VM.
