Umm title says all really, I'l attach a pic for you.

And what's with the tiny file size limit?

Edit: Can't upload cause it's too big(Rtarded)
It went sort of like this:
I entered my email address: elextro987@gmail.com in the email box,
then I clicked register(or something similar) then it had a box with "invalid" written in it, which pointed to that box.
Under that, there was a box which said "elextro987@gmail.com is correct"
I tried clicking register and reentering information but it would not accept it, does anyone have this problem?

Thanks,
