maemo.org - Talk - Media Player Glitch

Hi! I am New here. i just got my Nokia N900, and unfortunately I have experienced a glitch already :(

Just like my previous phone (nokia N95 8G) I wanted to use this one as an mp3 player too. So I started adding songs. The thing is that when I chose some songs I got this message "Unable to find media file" So I went to file manager, deleted the whole album (the problem was with 2 whole albums, except 1 song from one of the albums) and using Pc Suite re-added the album. But now in the Media Player it shows those songs twice! But in file manages and at my pc I can find them only once. By deleting the album again, I delete only one of the copy of the songs(the one that actually works) and the glitchy ones stays. I wouldnt mind if the player just skipped the faulty song, but when it encounters such a song, it stops and need to press the play button again.

I re-installed my firmware, hoping that this would format the entire phone, but that was not the case :( I dont mind formating it, as I only had it half a day and everything I need is still on my old phone.

Can anyone help me?Either help delete/erase the glitch or format the phone(I was unable to do so) so that everything will be as they were when I first booted it?

P.S One more thing I tried : In the media player, sorted by albums, if I tap on the album name I get an option to delete the files on this folder, I do so, and they stop appearing on the screen. But the player still reads them, and when I re-enter the forlder/album they are still there.

Thanks in advance guys and hope that you can help me :(
