package manager error

Binary package hint: gnome-panel

I just recently got Ubuntu and decided to get limewire. there seems to have been a problem with the installation and it does not work and i get this message

E: The package limewire-basic needs to be reinstalled, but I can't find an archive for it.

Iver tried alot of different methods to remove, like apt-get remove or purge etc. and nothing happens. since i got this error i cant download anything using apt-get or use package manager. I really don't want to go back to vista, i started to really like Ubuntu and the apt-get features on it and everything else.

Im using a hp dv6305us notebook with AMD Turion 64 x2. everything works fine but after the apt-get problems with limewire i cant do much with apt-get and package manager not working.
Im using Feisty 7.04
