Failed to burn DVD

So I turned on the computer to copy a dvd today with the dvdfab software that I have been using without a problem. Poped in the dvd and it did step one just fine then it asks to insert a blank dvd. I insert a very blank dvd and it says failed to burn dvd. So I pop in a new one. It doesnt work either. So I restart. It dosent work either. So I reinstal. And theres the new verson of dvdfab6 something so that works until step two. Same “Failed to burn DVD” message came up

Question: What do I do?

please post a log from my documents\dvdfab\logs

please give more details about the burn error, usually an error number such as 122

have you tried setting ImgBurn as the burn engine
