I foolishly tried to set up two libraries for two diff. ipods. Now my original library is changed and all the music I purchased is not listing. In purchased I see 906 songs - but I cannot get them to show up as a list - is there help out there?

I tried to set up two libaries so my two ipods could sync different kinds of music. This wiped out my original Itunes - I have been trying to get it back to the way it was. I have is backed up on Simple Save but do not want to plug that aback in since I am afraid it will then take up the new situation instead of allowing me to put the data on simple save back to the computer for Itunes. I want to show my 908 songs that I have purchased and I cannot seem to do this... It shows in purchased= as 0-8 - but I cannot get them to list. What am I doing wrong. I know I should have left it alone and never attempted something I know nothing about~ Thanks
