$10.00 dollar field tuning card

[bryan]

I recently bought a MMP/6900 combo, and it came w/a coupon for a free castle link wich i already have from my mmm or a tuning card for $10 this is a good deal so i want to take advatage of it. When i type the code # in it says invalid or expired code. Expiration date 08/01/11. I tried w/ cap lock on and off ,dashes, no dashes.Has anyone else had this problem.Hopefully someone from castle will read this.
