So i got a copy without the xenom intro, it said patched so i went for it. I loaded the game up and it worked fine. i saved it and took a break. I reload my r4 with r4wood and it says menu.dat missing. weird so i put it in my computer. EVERYTHING IS GONE BUT 1 FOLDER. the folder wont be deleted by even file assassin. it says its 3 mb but it says it using all the memory on my sd card. been using my r4 for years now, never heard of anything like this. help!?
