The test version which worked for DKD can be downloaded from the link in this message. I\'m sure Charlie would appreciate it if you could try installing that, and report back.

I tried to ping 163.1.124.171 (climateprediction.net), and of course, it works fine - no packet losses. So I can apparently reach the climateprediction.net servers ok. The problem must be elsewhere. any ideas?

Have you tried pinging climateprediction.net directly rather than the 163.1.124.171 address to which it resolves? Or is that what you meant?

denbarth,

BOINC is pretty good at installing and uninstalling while still preserving account and project data. Before resetting BOINC and losing your running models it might be worth a try. I\'m not very hopeful that it will solve your problem, though, because \"Couldn\'t resolve host name\" looks like a connection issue (DNS?) - though your other Internet stuff is, confusingly, OK.

I haven\'t needed to restore a BOINC backup on my Mac, but there does seem to be a permissions problem with the switcher. Until I\'ve worked out what really matters my backup strategy on Mac would be copy/paste away/paste back/reinstall BOINC. More experienced users might know better!

I read the threads on backups and made a backup copy of the entire Boinc data file in a different location. (Note: Les, I regretfully abandon the Bionic moniker. But it\'s a much cooler name!) Whew. That windows stuff is complicated. Using the supplied uninstaller, I uninstall Boinc.app, then reinstall. Run into a permissions problem, message is reinstall. That done, Boinc launches. For grins, I attempt to attach to climateprediction.net. Error message - can\'t successfully complete. Not a good sign.

So I cut and paste the backup data file over the newly created data file, and launch Boinc. Everything seems to be starting up an running ok.... and... nope. I have the same error as before. Can\'t resolve host name.

So.... it seems from the attempt to attach to climateprediction.net that my MacBook is not even able to connect to the project, much less resume the processing and upload of completed models.

I\'m going to search the initial install and startup forums carefully again and see if I can spot anything that is amiss in my network/internet settings. Since I attached successfully in the past, something must be awry...

I did a quick net search, and the following is one of the early posts mentioned: CNET downloads.
It says that the program encrypts connections, and that it stays there after you exit. You need to use an icon in the tray for that.
Looks like it\'s the problem.
