It seems to be a grey area whether Magic 2.0 is legal to download or not, since people who have been genuinely interested in a license in the past have not been able to contact the author.
This could be seen as either
A) The author isn't responding so doesn't really care who downloads the program, and hasn't made an effort to notify the Amiga community on the status of the project therefore go ahead!
or
B) The author has changed EMail address (?) and would still like people to pay for it
It is entirely up to you what you want to do, I don't know what the Moderators views are on this, since it is a bit of a grey area but you can get version 2.0 from
here although do so at your own risk!
