iPod Viewer Problem? HELP

Hello. I am a "newbie" to this forum. Someone will get the distinction of helping the "new guy on the block" with his first problem on this forum.

Suddenly, after loading some new software (MacKeeper), which supposedly
maintains and fixes problems on my iMac G5, my iPod Viewer that I use to
extract songs from my iPod will not allow me to do just that. The "Transfer Songs" or "Playlist" does not "highlight" allowing the song or playlist
to copy. Is anyone out there familiar with the iPod Viewer Application? It has worked very good in the past. Also, are there any other quality apps. that you recommend for copying song from your iPods. Please Help, Thank You All & Hello Again.
