Error saying "Tableninja Still Running"

Every time I try to open tableninja this error appears

Imgur: The most awesome images on the Internet

I open the task manager and tableninja is not running.

Was wondering if I could get some help on this please

Have you tried restarting your PC?

This is a real question? Yes...I have restarted my PC, uninstalled/reinstalled the program, searched the net for this very problem, but couldn't find anything related to it.

Your help would be greatly appreciated, thanks.

what version of windows are you using and have you installed any new software in the last few days?

WIndows 7, no new software so far as I can tell.

Hi,

Please right click on TN then go to Properties > compatibility > run as admin enable this feature then see if that works
