hello, im hoping i can get some help here because im at my wit's end. ive been having problems running roxio 2012 on my newest pc which i built myself. i am running windows 7 ultimate 64-bit with an amd 6 core fx 6100 processor and 16GB of RAM currently. i am able to install the software with no problems at all but when i try to burn mp3 discs using music disc creator my writes always fail and show the message "LUN not ready". ive googled and googled to no end and found absolutely NOTHING pertaining to this error message. i am super frustrated. i have uninstalled and re-installed the software multiple times and i've also tried this px engine fix to no avail. can anyone suggest anything else?
