How to get RX480 x6 on Windows running?

I got a few rigs running ETC now and i wanna mine ZEC.

Set up on on nheqminer_v0.2a_suprnova to the suprnova pool but got these errors:

Made a run.bat file with this:
nheqminer.exe -u Hidde_Hoogland.minerhome -p password -t 4

-t 0 -od 0 1 2 3 4 5 or -od 0,1,2,3,4,5

I dont see any errors. Seems to be mining fine
