Why I can't use Nero Burning ROM 6.3.1.10?

[morcamtec]

I upgraded to new Nero version. I always used Nero Burning ROM for backing up my DVDs with "on the fly" option. I tried after the upgrade but the software told me that like it is the first time to try a backing up "on the fly" it has to make a simulation first. But always appears the same dialog box. How I can Nero jump this step with 6.3.1.10 ? After that with old versions never it apperas that!!!.

burning on the fly is not encouraged, because of possible buffer underrun issues. it is safer to copy the files to the hard drive first, then burn with nero.

But I always have used "in the fly" option, including 6.3.1.6 version of Nero and never it asked that. I wonder why do it do now?
