software will not install

I just recently installed suse 11.0.
I have been using suse for years but never have i not been able to install software using yast.

My problem:

I try to install new packages with the installer, but when i do it stops after the first few or only one package and then asks “install any other packages” [Yes] [No].
I did an upgrade after installing my base system.
Does anyone know what went wrong?
