Some of my games not loading properly or at all. I havent been on my jtag for a long time but my games always worked perfectly. I have tried to load cod bo1, waw, mw2 and but I get a black screen or in waw's case the loading symbol flickers every few seconds in the bottom right corner but the the game never starts. I have redownloaded all the games thinking that would fix the issue but it hasnt. Other games still work like fifa, gta and far cry.

Also in xex menu i am unable to copy and paste from my usb to my hdd but i can copy from my hdd to other locations on it and i can copy from the usb to the hdd on the dashboard.

Is there any known fix for either of these cause i cannot find it online?
