Tried that with most of the IP's from this page

but I keep getting this error message.
"The remote connection was not made because the attempted VPN tunnels failed. The VPN server might be unreachable. If this connection is attempting to use an L2TP/IPsec tunnel, the security parameters required for IPsec negotiation might not be configured properly."
Any ideas?
Btw it was working fine again last night but now I got home from work and it's gone again.
I e-mailed wideVPN about this a day ago and still haven't gotten a reply yet I love how when I was inquiring about the purchase their replys were almost instant.
