Recenty, we have made a few major changes to our license usage terms for all our commerical products. The licenses for all our commercial products have an expiry period and will have to be renewed every year at very small fee. The support for our products at technical support center has also been made free till the license expires for the purchased product. When you renew the license, the free support is also renewed automatically. Please click here to know more on modified license usage terms, support and renewal options
