If the VPN connects whilst the firewall is disabled you'll need to setup an exception in order to use the VPN while the firewall is running.

In some cases customers have had success completely unisntalling the firewall and then reinstalling it whilst the VPN is connected.

- Windows UAC. Customers have found that disabling UAC will sometimes allow OpenVPN to work when all other soltuons have been tested.
