I copied and paste the key. Works for a few days then since, unable to authenticate. I purchased the lifetime key too. Also, read about waiting a day or two for bot to work after update but still doesn't (during time that I could authenticate). No option to send support. Sent using contact option but no response. Not trying to be difficult at all but I'm not getting anywhere. Looks like I'll do it the hard way and take it to PayPal.
