Having problem viewing my music

I added music to my new Sansa Clip, then added more music a few days later.  I can plug my Clip into my USB and click to view the music in Explorer and it only shows up the music that I added last.  I opened up WMP and it also only shows the latest music I added.  I can turn on my Clip and listen to all the original music.  What’s happening with this and why can’t I view ALL my music?  Help please someone!

Music added while you are connected in MTP mode only shows on your computer when you are connected in MTP mode; likewise as to MSC mode.  The solution:  always use one mode or the other.

Thank you for your reply - I certainly appreciate your help.  Would I sound too much like an idiot to ask what the difference is in this MTP and MSC mode? I read the user manual and it didn’t seem to explain much.  Thanks again!!!

Simple breakdown: in MTP the files are managed through Windows Media Player, and MSC the Clip is shown in My Computer as another removeable memory device.

Well, how simple is that?  Thanks for answering my questions.  I’ve already gotten everything switched to one mode and hopefully this won’t ever happen again!
