Too bad ... after a hard disk replacement become necessary, I had to download the software again and ... of course I did not have the key for the software. However, I had once registered myself, etc. from the manufacturer as a customer with serial number of the sticks. Prima: these documents I had! Without further ado returned to Elgato. Information: This is not enough, it would have the original invoices are submitted. Yes thank you very much! Other manufacturers operate fortunately not as a high-security limbo when sometime later drivers or software for a hardware device required subsequently. So now I have just ordered a new stick ... from another manufacturer!
