Every time I start up the G.E.C.K. for Fallout: New Vegas the Render Window won't open, I've never hidden it from view or changed any settings, but it won't open, I've uninstalled the G.E.C.K. and re-installed it, I've uninstalled the G.E.C.K., restarted my computer and re-installed it but nothing works, when I click "View" it doesn't have a tick next to it and the window doesn't open when clicked nor does a tick appear next to it, any help is appreciated.
