I wrote to NCH support about this but there has been no response yet.
I and some other associates use ED 4.04. There are some issues we're experiencing which may be bugs in ED that have been worked out in later versions. I would like to experiment with the current ED to see if it's less problematic. However when I installed the ED download from this site, it immediately reports that the trial period has expired.
If the newer ED version has the same issue as the version we now use (4.04) we won't upgrade. But I don't am not going to upgrade just to make the experiment. I don't know if the trial failure is by design or just a mistake in NCH's installer routines. Can someone clarify?
