I recently downloaded the new Boinc and restarted my projects after reinstalling my whole system after a series of crashes. Einstein@Home is doing no work, and I found these messages:

Look into stderr of the Tasks you reported. There I find:
2006-09-02 22:22:01.2110 [CRITICAL]: First object in file ../../projects/einstein.phys.uwm.edu/h1_0370.0_S5R1 (block 78) is not (double)1.0!
2006-09-02 22:22:01.2110 [CRITICAL]: The file might be corrupted

Thanks for the input.
