Can't play any of the tunes on my iPod Classic

Hi

Yesterday I attempted to delete about 20 songs from my IPOD Classic 80gb using Music Bee. I usually highlight the titles I wish to delete, then right click on them and click delete without any problems. However, on this occasion, the screen locked up and when it came back up, my IPOD was not showing any music (it had nearly 6000 songs on it). Further investigation has revealed they have gone into a new folder extension called 'storage', which when opened, has all the usual folders within it (calendars, contacts, Ipod control, Music, Notes & recordings). If I click on storage and then music, all my files appear and I can play them from that on my PC (through Music Bee) but I cannot play them on my IPOD away from the computer. Before anyone suggests using ITunes, my computer cannot accept ITunes for some reason (I have tried numerous attempts to get it to install), which is the reason I ended up with Music Bee which I enjoy using. I don't want to wipe it clean and start again as apart from the CD derived tracks, I have a lot of ones from other sources so this would take me many, many hours. Hopefully someone can help me. Thanks in advance. Peter
