I evaluated ext designer for a few weeks, over all it works well infactI even stated a project with it. When my eval expired I went out to the ext site an purchased a license. I now have a license key but I can not get into ext designer to activate it. I have tried to un-install and re-install it but I am still blocked at the entry dialoge box when I attempt to launch it. How can I access the software application I have already paid for?
