    SCAM! No matter how many times you sign in for student account, it just won't do it. Send you fake code that doesn't work and there's no other way around it. So I'm locked out from an application that's supposed to be paid for for me to use. SCAMMERS. READ ALL THESE FAKE REVIEWS WITH THREE WORD SENTENCES!! OH!!! BROTHER!!!!!
