Can't log into RC on phone.

Trying to log on with my phone (Motorola Droid X) And keep saying thank you and goes back to the sign in page pretty sure like when I first couldn't get on here.
I believe it was the cookies that had to be deleted last time and at the bottom of the RC page it says delete board cookies which i do but still won't let me log in.Any help?
