Blog Issues...Need help!

I'm trying to enter information and anecdotes into my blog. However, I seem to be having an issue and hope that either other people are having the same issue and call tell me how to fix it, or that I am perhaps doing something fundamentally wrong.

I will click on the page to edit my blog. I received the link in a u2u. I will input my username and my password. Then, all the login page does is refresh: It doesn't not forward me to the area in which I can actually edit my blog in.

Does anyone have any suggestions? I honestly have got no clue on how to fix this.

Thanks muchly

you have a u2u
