I already wrote a ticket about this issue (to be more precise, two tickets), but I am kinda afraif my problem won't be solved any time before the weekend.
I purchased the upgrade (35 $) via Credit Card, but the purchase was stuck at processing. The credit card successfully bookmarked the money. After writing a ticket about it, the response was rather quick, and the purchase was put on complete.
I was able to download the game. But I never recieved the mail with the license key. No mail, no spam folder, nothing. So now I am stuck with a downloaded game, which I can't activate, while being afraid that the support is off to the weekend. And I just need to get the mail with the key.
I already opened a second ticket with the marking "Urgent", and I hope this topic will also raise awareness.
