Sequel LE 2

after installing demos of sequel 3 and cubase elements I can no longer set preferences in sequel le 2 - it is greyed out. Also inserting the empty audio track into le 2 does not allow me to set the ci1 interface so I can not record audio into le 2 any more. please help

Hello,
try running Sequel as administrator.
If that doesn’t help you can reinstall the program.
