I just updated my version of efi live about 5 hours ago and I have been fighting with this for hours. I had 7.4 and updated to 7.55. I have noticed that the tune tool seem to get locked up more often (not loading up and not responding). After I loaded the drivers for RR and Flashscan I registered my efi live. I put in every number, letter, and got the date correct in the registration. I have done this about 15 times.
I have v1 flashscan so I don't know if that was the problem or not but man I wish I had my older verison of 7.4. This one has been nothing but problems for me. Does anyone have any suggetions?
