Before we go cutting things out of your system, try removing either of these two software / drivers:

Tunngle (Version: 5.8.7 - Tunngle.net GmbH)
OpenVPN 2.3.12-I601 (Version: 2.3.12-I601 - )

Both of these seem to be using the same base driver and this may be interfering with one another during loading. Let me know if this makes the difference for you.
