I'm getting an "argument index out of range" error with v1.4 on a 290.  Works fine on 1.3.2.  Tried changing intensity values, taking out "experimental-kernel" but no luck.  Anyone else?

This is my bat file:
optiminer.exe -s equihash.usa.nicehash.com:3357 -u someuser -p z -d 2 -i 6 --experimental-kernel
