Q: My hanbot used to work, but now it closes itself when checking for updates
A: Please connect using a VPN or Proxy as this issue seems to be caused by your network having a firewall that blocks the connection to the download server.
(If your VPN doesn't let you download the update, please try another one. I personally use dashlane's VPN feature to do this and have had no issues thus far.)
Q: I paid and I haven't gotten my key?
A: I personally recommend using gmail and it takes a few minutes between the transaction confirmation and the second email which contains the key to be sent out even then.
(Also please check all folders in your email, spam included. It's not instant, so you will have to wait a few minutes. My longest wait was about 15 minutes after I sent my purchase.)
