Hi advaya,
Can you clarify if you have imported your Semester 2 content file - did you double-click on the content file after downloading it?
If you haven't done this step yet, kindly double-click on the file you've downloaded previously to import your Semester 2 lessons to Little Reader (or you can simply insert your Semester 2 Content Disc which is included in your LR Deluxe Kit). You may also check if your Semester 1 lessons are complete (there should be lessons for Day 001 up to Day 130 in the Semester 1 course) - if you only have lessons until Day 009, then you should also import your Semester 1 content.
If your Semester 2 course still does not appear in the 'Courses' drop-down list in LR, do let me know
