Settings causes hard crash

Application crashes any time I try to open the settings. I have been having this issue for about a year now but have been able to work around it until now.

I've tested all releases from `0.7.0.0` to `0.7.5.0` and get the exact same results. Was unable to test versions earlier than `0.7.0.0` due to them not having signed certificates. This leads me to believe it may be an issue with my Windows install but since other users had the same issues in older versions I figured maybe there is a connection.

Below is the windows Event Viewer Application log:
```
