A coworker sent a mail to XVT support team last week, no answer, the mail came back with an invalid mailbox error message. So we mailed the sales... 3 days later, still no answer.
I google this morning to find XVT user group, what ever... it seem to be a top secret product.
Also very nice of you to have changed all of your functions name between 3.0 and 5.0.
Sadly I got that new job few week ago and they use XVT...
