You downloaded something that you are not entitled to. Or you have downloaded the wrong key type of this product. (I.E. YYMEA Instead of MTOOG)
Double check your key type by looking on the side of the Key for the five letters. Download the product with that key type listed.
*For VBSDN* Please don't download YYMEA, that is incorrect. Your key is YYMEA but your license is VBSDN. Please make sure you download VBSDN Products not YYMEA.
