I got a 1GB rca mp3 player for Christmas last year it was working fine until a couple weeks ago I deleted about 200mb to make room for some new music. It deleted all my previously saved music and the new stuff : ( I was only able to put some of the music back on because it now only had 700mb of free space! I tried reformatting it in FAT instead of FAT32 and now it tells me that I have 299mb of free space but it won't let me add any more files...I'm confused.

You'll want to reformat your player again, in FAT32, not FAT.
Don't forget that a player's memory capacity is measured differently by the manufacturer than by your PC. This will account for much of the difference, plus you'll need to figure some space is used for system functions of the player.
