Ok,this is the first time i post here,but I already got some info from here. My problem is below: I bought my DSLite 2 weeks ago,it came with a R4DSi and a 4GB Kingston MicroSD with some games. After a while,everytime i put the microsd on my computer i got the "do you want to fix Removable Disc(e?" message. I always did fixed,no problems there. But today, i put my SD on computer to transfer Professor Layton to it,then i got the message again,the "broken" files were sent to "FOUND000" folder. When i booted up again, the R4 menu was a mess of colors, nothing like my default winter theme. I played a litlle PL and then decided to try and fix my theme problem. When i put my SD back into the computer and try to acess it,the message "CANNOT ACESS DRIVE E: ACESS DENIED" showed up.I removed it(with the "remove with safety" button") and put it back in. I looked for the FOUND000 folder. by opening it, explorer.exe froze and i needed to restart it. Now,the only thing that shows on my Micro SD is "USBCÇ╗aƒ", an almost 2GB file with no extension. And I can't put anything on my R4 anymore. I want to know if i can fix this ( i can't delete USBCÇ╗aƒ it shows a weird error message). I need to admit that I believe all my files and folders are lost,so if there is no way to fix it, I will probably need a guide and links to "reinstall" the R4 stuff on my SD. Thanks in advance, Dusk.
