hashcat64 not working versus hashcat32

[Wushu]

So I have a strange issue and I'm not sure where to start troubleshooting.

After upgrading to 3.0 and installing the new nVidia drivers, I can't get hashcat64.bin to run.  If I execute the bin, even with just -h, it just spits me right back to command prompt without displaying anything.

hashcat32.bin works just fine.

I went back to the older cudaHashcat64.bin and that also works just fine.

Any ideas?

Thanks.
