You have to realize that Disney's pattern has NOT been to release new codes as soon as old ones expire. There has generally been a delay of 1-2 weeks before codes for the next period are released. They probably are assessing how big of a discount to offer based on their room occupancy numbers right now.
I know you don't want to hear it - but be patient! Tying yourself in knots won't make the codes come out faster. Make sure you have booked yourself something that you can afford and if a code comes out that makes an upgrade possible for your budget then snag it.
