The logfile previously attached was created using the drive with the region setting. I presume another one isn't needed ?
Why the need to only set a region once? Doesn't this contradicts the '5 times only" rule which is must in place when AnyDVD is not running? Yes /No?
If AnyDVD removes the Region code (as implied by the tick in Settings) isn't it then redundant? It would be helpful to know why it would cause unable to crack all CSS Keys error.
I don't think the message is authentic, as it happens on both drives, remembering one has a region set and one doesn't. I tried a couple of other DVDs and no such message is generated. Also the resultant WWTE file seems be be OK but I've only done spot checks so far.
Regarding multiple topics, maybe put something in the FAQ about avoiding that, as following the instructions precisely is what caused it. Thank you for fixing.
