SubsetSum@Home: validator up and running

I have the validator up and running, but it looks like there's some issue with things not validating correctly. If you get a result that doesn't validate against another please let me know -- i'm wondering if it's an operating system / 32 vs 64 bit issue (because i'm calculating an unsigned int checksum and they're not matching).Also, we're using BOINCs automatic credit generation, so let me know if that's working properly -- are the WUs generating enough credit? Do I have a decent flops estimate for them?
