Hello, I have a SanDisk MicroSD 2GB memory card for my phone(Samsung E900) but some of the files wouldn't play, I tried deleting the unplayable files from the phone but they wouldn't delete because of some file protection. At the time I thought it was because they were WMA that was the problem, but when i checked on the computer (Acer Aspire M3201 on Windows Vista Home Premium) I don't even have any WMA files on the card, They're all MP3. I then tried to erase all the music files from the memory card. But if i press delete on the keyboard nothing happens, also when i right click to the task menu the option delete isn't even there.
Can anyone give me any help or tips to fix this problem please.
