You're definitely not "****ed"! I don't even think you need to call them.
Just submit an Academic Change Request explaining that your stupid *ss listed a school you have not yet attended (did you list them as future courses when completing your Academic Record?) and ask them to delete it, since you did not list any class with a grade at that school that needs to be verified.
If they refuse, I assume you are enrolled in the new school for next month, so you should be able to order a transcript from them to send to AMCAS showing you have no completed classes. Either way, it will certainly get straightened out, and no, this will not blow your cycle.
