Unable to open accounts in Gmail, Yahoo and Twitter using Google Chrome

Hi all,
I can’t open my accounts in Gmail, Yahoo Mail and Twitter using Google Chrome Beta 2.
There’s an error telling me
Some Gmail features have failed to load due to an internet connectivity problem. If this problem persists, try reloading the page, using the older version, or using basic HTML mode. Learn More.

What’s the best solution if none of the three works?
Please give a solution.
Thanks.
