I've had to take my main Einstein @ home computer down for a while. It's been overheating like crazy when I run Einstein @ home! Luckily I still have it at work.
Oh, and just an update that there is a new version of BOINC available at http://einstein.phys.uwm.edu/ just go to "Download BOINC" and choose version 4.45. It's got some great new features!
