They don't appear to have any kind of support for their product, so I would suggest you try a similar program from Avanquest - Classic PhoneTools 9 click here. See if the trial works & is any good before purchasing.
If you need help, they have Tech support click here & a dedicated forum click here. G
P.S. After a few searches it appears the two programs are the same thing? Looks like Avanquest took over BVRP's CPT at some stage.
