Hello everybody !!
I have had a very big issue for weeks with climate prediction. I am using boinc 5.2.13, Windows XP on an AMD 3500+. So I have downloaded several files with Boinc, but the software refuses to do the calculations :

2006/01/18 17:02:08|climateprediction.net|signature verification failed for sulphur_data_4.22_windows_intelx86.zip
2006/01/18 17:02:08|climateprediction.net|Checksum or signature error for sulphur_data_4.22_windows_intelx86.zip
2006/01/18 17:02:09|climateprediction.net|Unrecoverable error for result sulphur_iei0_100858600_0 (app_version download error: couldn\'t get input files:<file_xfer_error> <file_name>sulphur_data_4.22_windows_intelx86.zip</file_name> <error_code>-120</error_code> <error_message>signature verification failed</error_message></file_xfer_error>)

I have detached from the project, then I have attached again, but it hasn\'t had any effect.
Well, I don\'t know what to do next.
Should I reinstall Boinc?

Try just resetting the project. It should delete the bad file and try again without the added agravation of mergeing hosts that detaching and reattaching causes.

Thank you for your reply!
Well, I still have the same problem, so I have subscribed to einstein@home to use my computer, instead of climateprediction...
