I have downloaded all the files except this one , BOINC has now stopped , any ideas?
Using BOINC version 4.05 and Windows XP (service pack 2)

climateprediction.net - 2004-09-16 23:26:13 - Checksum or signature error for hadsm3data_4.03_windows_intelx86.zip

One of the outstanding issues with BOINC is retrying download after failures such as you've experienced.

The best way to get round it is to click on the project tab, right click on the <b>climateprediction.net</b> project and select the <b>Reset project ...</b> option. If it fails to download on the second attempt try deleting the contents of your <b>projects\\climateprediction.net</b> directory before trying again. There is a limit of 4 model downloads per machine in a rolling 24 hour period, but you should get a successful download before hitting that.

Thanks,

Problem solved after reset.
