This error in your OpenVPN log file indicates that there are no TAP adapters available on the system for use. The TAP adapter is required to establish the Personal VPN connection.
One cause could be that the adapter was not properly disconnected from the previous session which could be the result of a system error or an improper shutdown - leaving it in the connected state.
Another possibility is that the TAP adapter has become corrupted and cannot load properly. Or, was inadvertently removed from the system.
To check on the status of the TAP adapter:
Go to Control Panel - Network Connections
Go to Control Panel - Network and Sharing Center - Manage Network Connections
Go to Control Panel - Network and Internet - Network and Sharing Center - Change adapter settings
--If the adapter shows connected after receiving the error, right click on the adapter and select 'disable'. Then, right click again and select 'enable'.
--If the TAP adapter shows 'disabled', simply right click and select 'enable'.
--If the TAP adapter does not show on the list in Windows Vista or 7, go to the Start Menu - OpenVPN - Utilities. Right click and run as administrator on 'Add a New Win 32 TAP Adapter'.
--If the steps above do not correct the problem or you just want to clear it from scratch, reinstall the SurfBouncer Personal VPN software. To do this, go to the download page and select the proper version. Be sure to uninstall the old version before re-installing. To uninstall, go to the 'Start Menu' and select the 'OpenVPN' tab and then select 'uninstall'.
