I have a v14 ps2 and I just recently installed free mc boot and esr on my memory card. It will load my backups randomly. Sometimes it will and sometimes it won't. I have taken my ps2 apart and cleaned it very well and I also cleaned the lens with alcohol and q tips. I used a flashlight to check the lens and I don't see any scratches at all. It's nice and clean. when it does load a back up it will play it flawlessly. Is there anything else I can do? Could there have been something wrong with the installation?
