Help mining

Trying to get Gminer or t-Rex to work mining Raven. I can get the programs to mine ETH just fine. Not at all for RVN. Using the bat files that come with the zip and just replacing my walllet address. Looks something like this

t-rex.exe -a kawpow -o stratum+tcp://stratum.ravenminer.com:3838 -u RGiv1p3VucxM28AzVYgNZcQH8C1nEEDe3d.rig -p x pause

I know you can change Rig name, and I have tried with no success either. Any suggestions to get it up and running ?
