Hi bud.Welcome to the forum!More Nero problems!Everybody's forums are full of Nero problems lately.
I'm not sure If it's a Nero bug or not.Have you tried aspichk to check your aspi layer?It seems that aspi layers are missing files when you upgrade.I used aspiinst first then aspi32 to correct it in my system.I have used Nero 55.40 with good results.
Sorry I can't give you much more...Maybe others are having the same problem.
