I would strongly recommend updating.  If you want to confirm that that's the 
issue before doing it, you could try

   strace ./pdftex.exe

If my guess is right, you'll probably get a pop-up saying that the entry point 
of some function can't be found.  "Some function" here would be a function that 
exists in cygwin-2.11.1 but not cygwin-2.9.0.

I have to leave now and probably won't be reachable again for the next 7 or 8 hours.
