oclHashcat-lite32.exe does nothing, immediately exits with no output.

[TwoBit]

I execute this:

oclHashcat-lite32.exe 5dXXX02abc4b2a76bXXX9d9110XXX592

and the app just immediately exits with no output. No arguments I give it cause it to do anything else. And none of the other exes do any different either.
