More than likely, your pH is low. If you can check it that will give some useful information and can get you back on track. If the pH is below 3.0, it really needs to be fixed or this fermentation may never get done.
You also look to be a little light on the nutrients. At this stage of fermentation the yeast won't be able to assimilate DAP very well, but if you give it energizer (about 4 tsp or 16 grams) and yeast hulls (1 gram per gallon they bind yeast toxins) that may help you. The nutrients tend to raise the pH slightly which may help, and if the yeast are hungry, this will help. Your racking has already taken care of aerating it further, so you should be okay from that standpoint.
Endeavor to persevere!

P.S. Just one clarification on terminology. What you have here is a traditional mead. A "Show Mead" is one made from only honey, water, and yeast, in which no nutrients are used (per BJCP guidelines).
