I have tried to run climateprediction first time on my older laptop---Pentium III-M, 256 MB RAM, 20 GB HDD and Windows XP SP2. After the BOINC switched between projects (from Seti@home) and wanted to start the climate prediction I saw a dialog box about Visual Fortran Run-Time Error, see below.

Hope it helps,

there are many users having this problem. take a look <a href="http://climateapps2.oucs.ox.ac.uk/cpdnboinc/forum_thread.php?id=480">here</a>

there was a problem in a batch of workunits sent out that had a bad namelist file, please detach/reattach and you will get a new (corrected) workunit.
