I cannot uninstall 'catblock' using application manager. What other way is there to uninstall?

This is what i was doing:
Just tried downloading and installing 'catblock' on app manager but it said unable to install. So i went to menu and it was there, i tapped it and it was loading then after a few seconds just goes back to what i was on before. Any idea what the problem is? I also just tried to uninstall and it said unable to uninstall. So now what, how do i remove it?

Also im app manager it says status: Broken but updateable.

I want to remove completly, how do i do this?
