Please don't send me to the how to thread for using cddvd gen. I have tried it already as well as neron thread. I am backing up Sonic heroes, I use Nero after I have rebuilt the files and it won't let me add the last files that take the total over 2 gig. It says choose another compilation. I have udf/iso selected. And my cddvd gen gives error about winaspi.dll I downloaded it and put in my system 32 folder and checked for the autoexec file which is there as well. What gives? Any help is greatly appreciated.
