I have paid for a premium version but it says unpaid and amount is taken from my Paypal!
Don't worry, if the amount is taken from your Paypal, then your payment through 2CheckOut has succeeded! 2Checkout review each transaction for fraudulent behavior through a series of sophisticated tools and business rules. Therefore, it takes 10-20 minutes of time to verify the transaction. After that, you can download your theme/plugin. Just login to your account and go to Services >> My Services. Click on the product name and you will get the download link in the next page. Let us know if you have any trouble to download the theme/plugin.
