After 4 months of bring offline, I'm trying to reconnect. I have a an 8-core i7 box with Nvidia GPU

I manually aborted several workunits, then triggered the "1 workunit max per day" mode.

Things still don't seem happy, I'm getting to the Internet through a tethered cell phone via T-mobile, and browsing and web surfing are all OK (but slowed to 10KBytes/sec while I'm over my wireless "quota") Here are the representative SETI messages:

What log files or debugging can I enable to figure out why tasks are getting
hosed on download? The only hardware thing I've done to the machine recently is add 12G of RAM, bring the total to 18G. My GPU is a 250-series, so I only have single-precision GPU, so Milkyway@home doesn't like me anymore.

Message 1191892 - Posted: 6 Feb 2012, 4:21:23 UTC - in response to Message 1188475.  

After my mobile ISP lifted my data rate caps, I can now download Einstein@home workunits.

However, SETI is still stuck in "HTTP error land" - this has been going on for nearly two weeks now... I set my BOINC download rate to 200 kbps , and Einstein at home cruňches just fine.

Is there a way to force download of a CPU-only SETI@home client? Seems prudent to rule out all the other possible issues....

Thanks!

Message 1191895 - Posted: 6 Feb 2012, 4:36:47 UTC - in response to Message 1191892.  

Also, based on advice in other threads in 2011, I've done a "reset project", which force a new download of .png files.

Are there any SETI Server problems that would cause this? Should I try downloading the files manually with wget? It seems like the problems are BOINC communicated with the SETI project servers.

I've tried manual download as well, and it returns a 502 HTTP error.
Einstein at home is running fine, but the BOINC/SETI@home combo can't
download:
    .png files
    workunits
    updated binaries and the files with names ending in _COPYING, etc.



What should I try next?

Lets try this way then.

And also I would recommend

and this if you want to crunch with CUDA
