Dear Kristin,
Difference is
your code: [wpv-if evaluate="'[wpv-view name="Courses"]' != '']
my code: [wpv-if evaluate="'[wpv-view name="Courses"]' != ''"], you forget about double quote in the end.
Please let me know if you are satisfied with my answer and if I can help you with any other questions you might have.
Regards,
Gen.
