Existing Microstudio users will receive an email by November 5, 2006 good through November 30, 2006 with a discount coupon to purchase version 3.000. When you receive your coupon, order immediately to get the discount. This is a totally new product and an upgrade is not available, except the discount coupon through November.
If you are an existing customer wait for your email or you will be paying for the product twice.
