Still getting this error (0x80040255) (latest version 4.5.8.7128).
If I exit the program and restart next set of CDs/DVDs is burnt OK. I asumed that the problem could be in that different media is used (for example, first copy to a CD/DVD of manufacturer A, and the second copy to a CD/DVD of a manufacturer B - and cdburnerxp would not check media properties (supported burning speeds etc.).
I am using Windows XP SP3 (though I must admit that this computer may or may be not up to date with the patches (this computer is off-line)).
Thanks.
