I have a 4.3E system menu, I can run the vc wads from system menu but when I put them onto the sd card menu via options it says, 'failed to launch'. I'm not sure why this happens. Also for some very weird reason, I can work only two games out of 10 and those two games were ones I installed before the ones I installed recently. The two I installed weren't before 4.3E or anything like that. Thank you. Hope this is fixable.
