I have purchased MC16 as upgrade via Paypal (Germany) but the registration did not work. As advised in the FAQ I went to the Paypal registration site and entered the transaction ID. The reply of the system was "Paypal Error":
We could not authenticate your transaction.
Please try later at JRiver's PayPal support page. You will need your PayPal Transaction ID.
Please visit Interact for technical support.
What is wrong? I tried this procedure several times on different days. Pretty annoying. The Paypal transaction was successfully completed. Please advise.
