Moving from Trial to Purchased package

I downloaded a CS Cart trial version over 6 months ago and installed it. Obviously, it has expired. I believe a new version has also come out in the meantime? I am now ready to actually purchase the cart. Since I have the older trial version installed, what kind of problems will I have converting to the newer licensed version? Iā€™d like to get an idea before I actually push the Purchase button. :slight_smile: Thank you.
