I know that this subject has been talked about a gigagillion times but nothing seem to solve my problem. First, I have always been able to burn cd's with my new computer super fast, all of a sudden it starts acting jerky, not recognizing disks,ect and when I finally get it to start burning again, it so slow (30 min a disk, opposed to previously 2 minutes) I wonder where the prob is? I check all my settings and diagnostics on the hardware and decide it must be with the free version of MJ8. I download the latest version and still no help, I decide to upgrade to the $25 version hoping that I can use some of the features and get some help. This brings me to the immediate problem. After paying and getting my registration code, the license will not install. I tried all the posts ( I think) and it still comes up " registration error". Any help would be appreciated.
