Default [Q] Can't run some applications after using System Tuner Pro

Ok, so I got over excited and have changed something critical to the way applications run. I can run most applications but there are a few, Smartpoint (which controls my wi-fi power switches) and Speedtest (Broadband speed test) now wil not run. They will start up but then shut down without any indication what is happening.

There was something in a diagnostic log saying that there was not enough memory to run the application, but that does not seem to make sense to me.

I am not sure if it is related but quite often I lose the ability to get to the WiFi settings and it does not show that I am connected to WiFi, but I am.

Any ideas how to revert changes or are changes logged that are done through System Tuner Pro?
