New update doesn't work – Classroom Organizer Review

I was Classroom Booksource's number one fan for a good 3 years. I had recommended the app and the website in general to SO many teachers. My whole library of 600+ books is organized using this app, but now that it updated I can't even sign in, the logo is over the sign in boxes. The website has even been showing an error message almost daily when my afternoon class tries to check out books. This has been soooo frustrating. I've had to have them write down their books and go back in and do it later. Defeats the purpose.
