I've tried everything including DB, nothing is working.
It's only been 6 weeks, you've barely crossed the starting line in this DB'ing marathon and you already want to declare it a failure? Look at some of the timelines around here, if you are expecting ANY positive movement from your W in less than a year then you are being far too optimistic. Sometimes WAS's will change their minds in less than a year, but it's fairly unusual. 1-2 years is more the norm, longer for MLC.
