Audio Files Lost In Dp 2.7

I did a search on this and nothing came up, so if this has been covered before please excuse me.

I'm running Digital Performer 2.7 on a G4 Gigabit Ethernet machine with a MOTU 1224 interface. Sometimes when I open a project DP tells me that one or more audio files are missing. I search for them, and sure enough they are missing. Often this happens on projects that I haven't opened in some time and decide to revisit.

A friend suggested that the resource forks of these files could be damaged. I'm no computer tech, nor do I have any disk repair utilities (I tried to install and run Norton, but all it did was crash my computer). I don't even know the reasoning behind rebuilding the desktop. Anyone's help here would be appreciated. Can resource forks be rebuilt if this is the problem? How can I tell and then remedy it?

This is just my home machine, so all this problem really does is cost me a few hours of work here and there, but I'm getting pretty fed up with it nonetheless.

Ideas?
