How do I get Adobe to "unblock" the 'Flash Player'?

I quit allowing the too-too frequent flash player updates because they seemed to be involved in a destructive process that resulted in my online connection reverting to configuration that was very, very slow (repeatedly). Subsequently, 'Adobe' advised me that they were "blocking" the software since I was not updating. While I can do without playing U-Tube, etc., it now affects my online banking, as well. I need to get this "un-blocked"! MAC Snow Leopard, Flash Player 13.
