Is anyone having a problem connecting to VOIP Buster. Whenever I try to log on I am informed that 'connection failure, unable to get a valid server address'. I've tried contacting the very inadequate help line and have been told to check my fire wall. I've tried connecting without the fire wall running and have re-installed the program - neither has cured the problem. The program did work until an upgrade was supplied by the company, since then I've had no luck in connecting. I would like to be able to use up my remaining credit before trying a different provide. has anyone any suggestions?
