Hey Ethan,

I'd highly recommend connecting with KrejsX on Skype to get a much quicker response (especially when he's awake, Australia's GMT +11). Ping him with your forum name and PayPal transaction number (so he can cross-reference your receipt) and he'll sort you out directly over Skype (he'll generate a license key for you and send you the authorization link to download UdemyDL (currently on v0.0.8 )
