Hi, how do I add 'flash player' to my new computer? It says I have to disconnect 'something' How do I do that and re-connect it back?

Another thing, I can't get into my e mail. It was working then something got disconnected. I think having to do with firewall. Some directions say to go to 'tools' and options, then security, then I get stuck not sure what to do then.
It lists like 3 areas -enable or disconnect' don't know what to do.

Thanks for any help. loretta
