i am starting to use Adobe LiveCycle Designer ES Version 188.8.131.5244.1.471865 and Adobe Acrobat 9 Pro Version 9.0.0.
Any File i like to see a preview in LiveCycle Designer only shows an Acrobat window with blank screen and blank Errorwindow like
Some times i have the same problem with my FireFox. But after Restart of FireFox all is running well for some days.
At LD i can start it or reboot the computer as often as i like to do but the problem is still the same.
I had the exact problem with Adobe LiveCycle Designer 9.
Firstly, to allow LD to use Acrobat Pro 9.0.0, I found I had to removed Reader from my system.
After this, I started to get your error.
Upgrading Acrobat to verion 9.2.0 fixed this problem for me.
