Download vertminer 0.5.3 https://www.dropbox.com/s/7nwv3wyr90imvj3/vertminer-0.5.fre3.zip

Use your normal scrypt config but remove --scrypt since vertminer knows the algorithm already...  Lower TC, lower powertune, w256 and expect half of the h/s compared to LTC.

Captain may have more to add, cause I use sgminer...

Windows build and example config: http://cryptojournal.blogspot.com/search/label/sgminer

My sgminer config is also on this thread...  Can't wait to see your hashes... Good luck!
