Same thing happened to me. You should clear cache & data by: M+Power Button in the beginning > Scroll down to Recovery Mode > Click both volume buttons simultaneously > You know what to do after this.
Actually, I might not. It might be obvious when I go to do it but all the instruction I've ever found for working with customs ROMs has been vague. Perhaps I can start keeping notes of what I do right/wrong to help with documentation. That would be more constructive than me complaining.
