I'm really sorry you're having to go before a review board, I can only imagine how scary that must be.

I don't want to seem like I'm being critical of you, but as you posted the email exchange, I thought it might be helpful to hear an outsider's view.

In your second email to your professor, you start with "it wasn't my fault." In a professional setting, that's just not something you say, even it something really wasn't your fault. Rather, one would acknowledge that something unexpected has happened and try to fix the issue. Claiming something isn't your fault (even if that is true) tends to annoy most people in a position of power. They don't usually care whose fault something is, they just want it acknowledged and fixed.

In your professor's second email, he's trying to nicely end the conversation, but you continued it. In his third email, he tries to end the conversation more firmly and even expresses some concern about your professionalism. Then, the last email from him very firmly closes the conversation. It seems like your professor was a bit taken aback by your insistence on getting answers from him. At that point, it probably would have been more beneficial to request a face to face meeting as the continuing emails just came across as demanding and disrespectful from your side.

Perhaps the professor could have been more understanding or more willing to work with you. Perhaps he really is an a-hole. It doesn't matter. You will need to learn to deal with all personality types in a professional manner, especially if you wish to be a therapist, which is entirely about interpersonal behaviors.
