Update Feedback fails

Updating to Xojo 2014r1 works fine on Mac and Windows. Unfortunately Feedback forced me to get update, which worked fine under Windows, but getting and installing the dmg for my Mac installed seems to give problems. Downloading this dmg goes dramatic slow, and once I have it downloaded it says that it cannot continue installing because of occupied resources. Restarting OSX as well as trying to install manually didn’t help me.
Can anybody tell me if this is a known problem ?

Oops, I see many of us had the problem while installing Feedback. Downloading manually helps.
