Thanks for the response. Contacted Paddle. Turns out I renewed in Feb this year but the 'Bot' cant give me the licence key, instead a rep will contact me soon regards this issue. I now realise how important it is to keep keys etc on a completely different system.

Hello I have an active subscription with Filebot, however due to hardware failure and total loss of database I no longer have a registered key. I cannot remember how I paid for the subscription, ie debit card etc, but It was active before the crash. How can I obtain a replacement key

Many Thanks.
