Everything looks normal from this.
Can you please create two files "asu.buffer" and "asu.debug" parallel to the AdobeUpdateServerSetup.log and then run the tool.
It will provide much more information on what's happening.
Aside from this problem, are you facing any other issues? Are the updates getting downloaded on your machine?
PS: Since that log file could be huge, it would be better if you could mail me.
