Not receiving WU's

(moderation:
Ever since SETI started having it's current outage, I've been having trouble getting Einstein WU's to download to my computer. However, I now have 25 or so WU's listed on my results page as "In Progress". I'm running version 4.43. The only other project I'm on is SETI; and those have been trying to upload since the 23rd. (On that day all my WU's on both projects were done.)
Here's where it started:
2005-08-23 19:37:00 [Einstein@Home] Finished upload of w1_1207.5__1207.9_0.1_T16_S4hA_4_0
2005-08-23 19:37:00 [Einstein@Home] Throughput 2219 bytes/sec
2005-08-23 19:37:01 [Einstein@Home] Finished upload of w1_1207.5__1207.9_0.1_T00_S4hB_3_0
2005-08-23 19:37:01 [Einstein@Home] Throughput 1796 bytes/sec
2005-08-23 19:37:02 [Einstein@Home] Scheduler request to http://einstein.phys.uwm.edu/EinsteinAtHome_cgi/cgi failed
2005-08-23 19:37:02 [Einstein@Home] No schedulers responded
2005-08-23 19:37:02 [Einstein@Home] Deferring communication with project for 1 minutes and 0 seconds
I got this also:
2005-08-26 20:45:06 [---] Insufficient work; requesting more
2005-08-26 20:50:07 [Einstein@Home] Master file fetch failed
2005-08-26 20:50:07 [Einstein@Home] Deferring communication with project for 8 minutes and 5 seconds
I did get one WU, which I've finished and am back to having the same trouble:
2005-08-28 11:50:53 [Einstein@Home] Requesting 8640.00 seconds of work
2005-08-28 11:50:53 [Einstein@Home] Sending scheduler request to http://einstein.phys.uwm.edu/EinsteinAtHome_cgi/cgi
2005-08-28 11:50:55 [Einstein@Home] Scheduler request to http://einstein.phys.uwm.edu/EinsteinAtHome_cgi/cgi failed
2005-08-28 11:50:55 [Einstein@Home] No schedulers responded
2005-08-28 11:50:55 [Einstein@Home] Deferring communication with project for 41 minutes and 19 seconds
I have re-started the computer several times since this started. In fact, I've shut it off for hours at a time...(no WU's & all)
Any help or info you can give this relative newby would be nice.
thanks.....

This appears to be the common ghost work-unit problem, where the server thinks WUs have been sent, but the computer does not have them. The server has a protocol for dealing with this, but it only works with BOINC 4.45 and later. Details can be found at http://einsteinathome.org/node/189626 ,but the end result is the server will re-send the lost WUs, and extend the deadlines to some extent. In your case, you'll probably need to manually abort WUs to make your deadlines, as you will have trouble doing 25 of them.
