can't update bitdefender

I have bitdefender and it says there is an update that needs to be done. I click on the update and it never finishes loading.  I keep getting an error message 1016 and it tells me to check my internet connection.  My internet is working just fine and I also disconnected it and tried to update using my phone as a hotspot and it won't finish.  It gets to 98% and then gives me the same erro 1016 message.  How can I fix this?
