Thought I was the only one. I opened a thread on this not too long ago. As a temporary solution, I use the airbusconnectextended.exe from the a318/a319, and it works flawlessly with both the a318, a319, a320, and a321. If I use the a320/21 version of the program, I also get the black mcdu along with the "failed to open image file" error. If I use the a318/a319 version and then try the a320 version, the a320 version displays the last image file that the a318/a319 downloaded, but nothing works (i.e. it is the same as when it is black, but with an image file this time). I am using the latest Windows 10, with fsx + acceleration.
