currupt file

I posted this on the message board haven't recieved any help:

I'm running setiathome on solaris 8 and 9 and I have been seeing this message:

  Done with work unit.
  Sending result - connecting to server.
  Program file corrupted

I can't tell if the work units are being send or not. When I restart seti the 
program downloads the next work units, but then does it again.

I downloaded the file from the seti web site. I did rename it to setiathome, 
but I did this in the past with no problem. I downloaded the same version 
twice with the same results. The file on the seti site is 
"sparc-sun-solaris2.6".

I have also tried to remove the *.sah files, with no luck.

Thanks for any help you can give.
