[SOLVED] unable to use the package manager

Hi all!
I cannot see anything in the package manager. I've got all the basic sources but the manager itself is not working;

As you can see, I hope. everything is grayed out. Everything else is working. I am posting from Mageia and can do everything I want on the internet so it is not a networking problem.
Any suggestion anyone?
