I posted this before in another topic but didn't get any response...
I know that 220.127.116.11 is supposed to fix issues, but this is the problem I had.
Nero 6 has issues with SP2 at least on my computer (latest update on the website from August 13th). This is the problem I had... it only occurs with Nero Express, not regular Nero.
Start up nero express. Create a new data DVD. Drag a few files over. Then drag some more (number doesn't matter)... program instantly crashes. I was able to reproduce the same thing 10 times, no matter how many files I dragged over in Nero Express. regular nero had no problems.
I had other issues with SP2, so I decided to go back to SP1. The nero problem (as well as all the other issues) went away.
