Hello,
today in the morning I found my client detached from SAH. Now i try to re-attach but get this errors:

http://setiathome.berkeley.edu/ - 2004-07-21 08:59:21 - Scheduler RPC to http://setiboincdata.ssl.berkeley.edu/sah_cgi/cgi succeeded
http://setiathome.berkeley.edu/ - 2004-07-21 08:59:21 - Message from server: Server can't open log file
http://setiathome.berkeley.edu/ - 2004-07-21 08:59:26 - Resetting project
http://setiathome.berkeley.edu/ - 2004-07-21 08:59:26 - Detaching from project

Additional a pop-up appears, saying: "Boinc failed to log into setiathome.berkeley.edu/. Please check your account ID and try again. My ID is correct. Whats the problem?

Greetings,
Andreas Voßloh

Several of us at least are getting the "Server can't open log file" message back from the server. Looks like the project is down. The pop-up warning is normal when you are trying to attach to the project when it is down. As long as you are using the URL and account ID from the e-mail you got you are doing everything right. Just keep trying but it might be down until the people at Berkeley get to work in the AM.
