input error when reading a case

[Raffe, Sydelle, SSA]

I'm running SPSS 15 and am getting the following error message  when accessing any of my spss sav files:
 
                >Input error when reading a case.

                >This command not executed.

I've used the files before and it appears to be accross the board (all my files). Ideas?
