No problem, I guess you're talking about this pool released with Level 53.

There is a bug that allows you to upgrade your pool even if you don't have it yet; by tapping it in your friends' towns(also see the comments on it's page).

So most likely your pool will already be upgraded once when you buy it.

PS Is your computer working again?
