Facebook Problem.

[Brighter.Tomorrow]

So, anytime I log in to Facebook now, I get told about Internet Security and that I should use a secure network, shortly after logging on it'll log me out and won't allow me to sign in via Blackberry. I've changed my password 4times and it's still happening. Any suggestions?
When I sign in, it sends me to: https://www.facebook.com/checkpoint/

Go to account, account security and then check the Https box, that should sort it. It worked for me :)

Something similar happened to me with Gmail. I cant figure out why, I put my security and spam blocking down like it told me and it still gave me that same message.
