How much time does it take?

[Nidhogg]

It's not the first time i buy gold, but other times i bought it on evening, then i went to bed, and on morning i had gold units and other features...

But now i bought gold on morning... how many time do i have to wait to get the account upgrade?

[Jeffery]

Until they upgrade it.4

Seriously though, there is no set time for upgrades to happen.Generally it will be within a day of submitting (if the paypalgoes through) but can be longer.
Just be patient,and wait. The game isn;t going anywhere.
