First off, I was browsing my music, when suddenly my phone told me there were "no files" for all of my artist. So, I thought just was just a slight glitch, so I tried to restart it. It turned off fine, but when I turn it back on again it freezes at the 'sony ericsson' screen, and doesn't do anything from there. I tried recharging the phone, but my phone tells me "cannot charge, you must use a sony ericsson charger" but I am using a sony ericsson charger! Any help please?
