Hi, I am thinking to buy it. But I have few question regarding serial no. 1. Will my serial number will work for all version like 2.07 or 3.0 or 4.0 or all up coming version ? 2. it is life time free for all version ? or I need to pay for upgrade version ? 3. my serial will work on only 2.07 for life time ? other upgrade will be payable ? Thanks.
