All it showed was couldn't communicate with project - server may be temporarily down. Internet access OK.

Earlier in the day when I was trying to attach some machines to Rosetta I had BoincTasks hang up. I waited for 10 minutes and then killed BTasks using Task Manager. That may have caused a glitch and 1 BOINC instance on 2 different machines got screwed up. After correcting the preference file on both machines they attach and pulled work without any problem.

BTW, they did attach without any problem. It just couldn't finish the WU and executable downloads.
