I upgraded 3 devices from BOINC 5.10.45 to 6.2.28 over the last couple of days. The last one was a few minutes ago. Following re-boot (WinXP x64) I see the following in the log:

11/25/08 9:33:36 PM|World Community Grid|Sending scheduler request: To fetch work. Requesting 103680 seconds of work, reporting 0 completed tasks
11/25/08 9:33:41 PM|World Community Grid|Scheduler request succeeded: got 0 new tasks
11/25/08 9:33:41 PM|World Community Grid|Message from server: Server can't open database

and the Pojects tab shows that communication has been defered for 60 minutes.

Installation directories are:
C:\BOINC\ = Program Files
C:\BOINC User Data\ = user data files

This is the same as the other 2 devices (WinXP x32) which came on stream without problems.

Install showed the same sequence on this device as the other 2 and there were no error messages during the install.

What I did prior to install was to suppress new tasks. After all tasks had completed I shut down BOINC 5.10.45 and installed 6.2.28 without removing the 5.10.45 version. Following install I let the device re-boot. After startup completed I selected "Allow New Tasks". The above log entries were entered about 2 minutes after doing so, which looks to me to be about right under the new application rules.

Log time of day is US Central Time Zone - Standard Time / UTC is plus 6 hours (11/26/08 3:33:36 AM)

This appears to me to be a Server restriction, but given it is a new installation on a 64-bit OS perhaps it's a device problem.

Any thoughts/suggestions on where the problem is?

Thanks in advance for any assistance/support offered!
