Latest Version 1.20 is now available. If you have the download version & you bought from Aerosoft, go to your accounts page or Your E-mail links & download the full version again. I know, it's a large file but the patch by itself has not been posted yet as of this writing.
With only a cursory test, I can tell you that the 33rd. start point no longer has a "Access violation" error.
The acceleration is smoother. Controller notches have changed slightly.
There is no longer a problem with stuck red signals.
I will do a more thorough test later, although I'm sure others will also do it.
Edit: Update V1.20 only file at 10.57 MB is now available at aerosoft's Faq/Update page.
