Ok! But how come they dont answer??
I think I know why.
When you sent me your PM you did not enter any text in the Subject field. All it said was
(No Subject).
That's okay here on the forum but if you wrote to Amanita Design support and did not enter any text in the Subject field you can be sure they thought your email was SPAM and never bothered to open it.
Try writing to them again and THIS time compose some Subject text that will explain what you're asking for. For example, try: "Lost my download link for Machinarium"
