What is the difference between...?

What is the difference between Cubase LE AI Elements and Cubase Elements?
I thought that I had cubase elements but it says that I can upgrade to Cubase Elements 8 for 49$


Click to About Cubase. Then you will find, which version of Cubase do you have. Also in the eLicenser Control Center, you can find the exact name (license). There are some differences, but there is no comparison chart of Cubase LE/AI/Elements, unfortunately.
