Whether to upgrade we charged again? because what we have today is Active X igrid 3.0 full version

According to our rules, you can upgrade to any new version of the product for free during the period of 1 year following the date of your purchase. After that, you need to renew your license to get this ability again. Generally the cost of a license renewal is about 50-60% of the original full price.
