Installed the upgrade and now all I get are error messages that things can't be found. . .grrrrr.
And to answer your question Michael, I bypassed ADE at a time when it was cumbersome and difficult to use and not at all user friendly and went with AFX because it resembles the original Lee Swordy utility AFCAD which I was familiar with and so the learning curve was almost nil. Also, AFX works across platforms so I can work within both sims seamlessly.
ADE may be a very good program and the price is certainly right. . .it was just a case of bad first impressions and I decided on a different direction.
