Can you try with this beta please. https://bitbucket.org/Gensplejs/publicfiles/downloads/Brightness%20Controller%201.5.2%20Beta%20Setup.exe

It has .pdb files included and will provide a better stack trace with line numbers for me to analyze.

Also what OS version are you using?

Sorry, I didn't realize the stack trace info didn't include the corresponding line numbers when I pasted it. I'm using win8 x64.

Ok... Can you try with the beta version i linked... that should give a better stack trace...

Any chance you could post the information again if the problem is still present in the newest 1.5.3 beta?`
