Well, as I said, the proper place to ask for support is in the thread. I'm not sure what else to suggest. That is where the author is most likely to look to see if anyone needs help.
(Also, PM Quick Reply is a modification also. So you are probably going to have to debug and modify the two modifications to work together. I wouldn't expect the modification writers to be able to fix it for you if they don't have the modification installed also.)
