welcome to the wonderfull world of evox ladies and gentlemen.
time to change your dashboard my friend. I went thru this a couple weeks back and ended up changing my dash over to MxM. very time consuming, but EVERYTHING runs fine now.
EvoX sux, theres no secret to it, the devs stopped updating so its been passed by by everything, even XBMP as a dash is better now.
or you can unhook the network cable everytime u use XBMP. thats your choice.
but seriously man, it sounds like youve had your xbox modded a while. you're not a newbie anymore.. you can upgrade now.
