Cannot connect to VPN Server

Upgraded to Yosemite last night and now my iMac can't connect to my companies VPN server.

My error is “The PPTP-VPN server did not respond.”

The error log at my company's VPN server is...

Log Name: System

Description:

A connection between the VPN server and the VPN client 69.132.54.71 has been established, but the VPN connection cannot be completed. The most common cause for this is that a firewall or router between the VPN server and the VPN client is not configured to allow Generic Routing Encapsulation (GRE) packets (protocol 47).

Hope there is a solution to this problem. My MacBook Pro on the same network running 10.9.5 connect just fine.
