Hi Cvetkovski,
I checked our backend and our paypal account.
In both places, i am seeing your previous order is "pending" which means, unpaid yet.
You can check your credit card (if you use your credit card to purchase) or paypal account (if you used your paypal account to purchase) to be sure that you haven't paid yet.
You can disregard your previous order and place an another order to try again. (the "pending" orders are periodically deleted, so don't worry about your previous unpaid order)
Regards.
