Want to update my grades on AADSAS but...

I got a C and a C+ in two out of my 4 courses. I've never earned grades this low before. However, schools I interviewed at asked us to always update them with grades sent to their school to show that we are still interested in their school..(one school stated that) Im waitlisted there now...should I still send them my grades to show my interest, even if they are bad? I dont know what to do!
