I am having trouble activating my CUBASE LE5 software and have downloaded the latest version of softwareinformer but now cannot activate the software. I now have no option to enter my registration key. Help!!!
Not sure what exactly you downloaded (the Software Informer client doesn't quite do anything to other programs on its own). It is possible that with the activation code included with your Cubase LE, you are not eligible for later versions of the program. Try removing Cubase altogether and re-installing it from the disc provided with the soundcard (or whatever the LE thing was bundled with).
Here, have a look: http://www.steinbergusers.com/cubasele/le_support.php - they can explain what you actually can do with the Light Edition.
