Comodo 4 and MSN Live on windows 7

That did not fix the problem.

Edit: Running it inside the sandbox actually did kind of fix the problem. It’s running in the taskbar but it crashes within a few minutes of use.

Is MSN live (& all related executables) still a safe files? (have a look, they sometimes get bounced). If not is it or any related executable) getting sandboxed? Please look in the D+ logs, immediately on reboot and after opening the app. Please these as screenshots with all info visible.

Then reboot and try again
