Wont let me add classes

The app worked great during the 2013-2014 school year, but this year it wont let me enter in the class I have (create a schedule). I paid the 1.99 for the pro version and really wish I could get this app to work again like it did last year. Also, at my school days alternate, red days and white days, switching off every other day. So a "red Monday" occurs only once every two weeks before it come around again, same with white Mondays, red Tuesdays, white Tuesdays, etc... Wish there was a way to add that in.
