its a pretty secure site like you have to put in a password right away try it out its www.miatech-advantage.com/exchange

Hello,

That site isn't working for me either.

it works from other computers i was at school earlier today and it worked and my moms place too... idk maybe its a firewall setting or something common

Hello,

Disable your firewall and see if it works.
