This last UPdate has MESSed UP   X-Plane.    It boots and runs????  However,   The pull down menus at the top - don't "Pull Down  - Big problem,   can't change Airport etc. etc.  
So What to do:  My thoughts: 
Yes, I understand this will at least initially be more work.   
Change the organization of the Software AND the Update  AND the recovery  Process.   So.  
1.  For Starters;  Separate  the Maps from the  Operations Software
2.  Provide Updates separately    One for the Operation Software and a Second the Maps.  
3. Provide roll back for each - so you can get back to your operating X-Plane.    
I can provide more detailed thought but I am sure you get the idea.  
Why:    I just did and upate and X-plane is broken as I have just outlined.   I have to install everything again - AND I have to do the Three Screen Setup etc. etc. and all the Yoke and Rudder Pedal options etc. etc.  What a pain!   
The other issue will be - there are a number of updates since my install  DVD's  - Where to stop so I do NOT repeat this  Mess again.   
If anything has been addressed on this - and I just don't know it.  Please advise me.
