Hi scottmandu,
Are you able to ping the servers you're trying to connect to? Has anything else in your environment changed since the last time you were able to connect, like your modem/router? Typically when I've seen 807 errors, it's been a NAT related issue, where packets on port 1723 (the well-known port for PPTP) are being dropped. If you're able to ping the servers you're connecting to, then you should try port-forwarding 1723 (TCP) on your router, restart the router, and see if you're able to connect then.
