Registration "Weird" Issue Please Help

I purchased and registered Cubase LE4. It came with a little Lexicon interface in a package deal. On the box it says Cubase LE4. So, i go through all of the steps to register the product and it registered fine online. I then however noticed that everytime I start the program it still pops up saying i need to register it and i have so many days and uses left. Well, i couldnt for the life of me figure out what was going on because Ive went through all the steps to register. I then pulled out the installation CD and noticed…the CD was Cubase LE5 not LE4. Which is not what it says on the box. So i registered version LE5 as version LE4 and im guessing thats where my hang up is. Anyone have any idea of what to do?

Thanks in advance.

Delete the LE 4 registration and register and activate the LE 5 version…!?
