Hello,
Sorry to hear you are having issues. First, need to see which, Fences or Start11 is giving the issue. Uninstall both. Reboot each time. Than install Fences 4, reboot. Test it . if there is issue when Fences only installed report back here. If it okay, install Start11. Reboot and retest. If have issue appear, report back here.
Thanks
