Unable to download

Hello, I paid for fritzing on my macbook, and then i went on my pc to the download page and it is asking me to pay again. When i go on my macbook, it still asks me to pay again although I already did.

Instructions for downloading are automatically emailed after the payment. Make sure to check the email account that was used for the payment.
If you are logged in during the payment, or use the same email address for payments and your login, it will be automatically connected to your account.
