When I signed op for a free and a basic plan can I login to both?

No, when I signed op for a free and a basic plan can you cannot login to both. Under one account you can only use one kind of subscription. The program remembers the last subscription you bought. When you first bought a free plan and then a basic plan, you can only login to your basic plan. In this case you have to set your links on the WebPages you want to Optimize.
