Beanstream payment module

[Miles]

I am setting up a site for a client using the Beanstream payment module. The trouble is that when I try to test a payment I get a series of errors:

 

Warning: session_start(): The session id contains invalid characters, valid characters are only a-z, A-Z and 0-9 in /Volumes/Circular/WebServer/testing/catalog/includes/functions/sessions.php on line 68

The only mod I have from stock OSC 2.2ms is the register_globals patch (register_globals is off)

 

Is that what the problem is? Is there a way to patch the beanstream module?

 

Thanks,
