Help upgrading.

[M1ntyFr3sh]

Hi there. I need help upgrading. I type my username after it says premium upgrades, I click on donor iron. I click on add to cart then it just kicks me out to enter username. I tried it many times but it does the same thing. If anyone knows please help me. ( I am already logged in)
