I've found a solution!!! If you have an error U43M1D207 try to download an update from ACC (take note of hour and minutes). In Mac OS, go to Username/library/Logs/AdobeDownload/DLM.log You'll find at the end of the file (corresponding hour and minutes) a string like so: The file to be downloaded is http://swupdl.adobe.com/blahblahblah etc etc. Copy the link and paste in Safari, download and manually install it. Now close the AAC. Relaunch it and redo the same thing for all the errors. It worked for me! It's incredible Adobe don't find a solution and a simple user find a workaround... and post the solution instead of a link to the same useless discussions! Sorry for my bad english!
