I can't Log in??????

The link is a screenshot of what is going on, I am lost as hell about this.... I cannot click the screen, my internet works and everything is fine. I have no clue what is wrong but, I cannot even click the password entry box to log in. Help is appreciated because the issue reporter rarely is helpful for me.

If anyone knows whats wrong help is appreciated, I have tried restarting my computer and this patch I have had to basically revert to an older version and restart the client almost every time I log in. Please Help.
