Joan's advice was excellent. Your new agent will handle it, smooth over any rough patches , and present your offer in the best light possible.
The only thing I would add, is, if you are fearful that you past bad experience might hurt your chance of buying this home, I wouldn't worry. Remember, the listing agent represents the seller now, and it is in her and their best interest to put this sale together, regardless of any unpleasant past experiences. If you feel that, for any reason, you are not being treated fairly, once again, your buyer's agent can handle that, as well.
Best wishes with your purchase!

I hope you find comfort and confidence in seeing that all agents have the same advice for you: FIND A GREAT BUYER'S AGENT! They are out there, and they will take care of you. Let the buyer's agent earn their paycheck by dealing with that other agent. The listing agent's job is to represent their seller -- not you; so find someone that is only interested in getting you the best deal possible. Good luck!
