I use another browser (Internet Explorer), but sill gives me the same problem

Did you activate and verify the email address for your wallet?
I don't even received the email, am I skipped something???
When you signed up for an account on the site, and went to your "wallet" it would have prompted you to put in an email.
Did you ever do this? I am assuming you did if you can see the withdrawal screen. What email did you use for this?
I searched my inbox with "uptweet" keyword, and didn't find any mail

And I used Gmail
Please PM your gmail user name.
Also make sure that you check in your SPAM folder to make sure your email is not blocking it.
