Can anyone help?

[spadekevin]

Hello,

I am a newbie running Linux Mint 15 Olivia Cinnamon Edition 64-bit. The Software Manager and Update Manager just stopped working. When I try to start the Software Manager, it asks for my password but then nothing happens. The Update Manager gives me a message which says "Could not refresh the list of packages." Can anyone help?

Please help.

I didn't find the right solution from the internet.
