July 13, 2014: We have just made some changes to our software. If you’re a customer who has studied using our software in the past, you should clear the cookies, cache, and temporary Internet files from the browser you are using. New customers are not affected.
If you don’t know how to clear your cookies and cache, do a Google search, inserting the correct words for your version: “Clear cookies and cache in [browser name] on the [operating system].” Obviously you need to know the name of the browser (Firefox is an example) and the type of operating system (for example, Android or Windows) you are using.
If you are seeing any strange behavior in our software while you’re studying, clearing the cache is very likely to solve the problem.
