Sorry for delayed response, I was offline for two days. I have replied you privately, for any case will duplicate my suggestion here:
From the recent experience I have got from one of the customers, I have a conclusion that some instruction in the README file is not certainly clear. Especially, it affects the parseMessage function. Possibly, your problem is related to this, too. Unfortunately, I was still not having enough of time to fix this instruction, will do it ASAP next week.
So, just to repeat: bb_plugins.php should have TWO parts of the add-on's code inserted. One is located in bb_plugins.code.txt part and should be pasted directly. Another one is located in bb_plugins_parseMessage.code.txt (or similar name - sorry, I do not remember it mutually, typing this reply from my mobile device with no having access to files) - that one should be pasted in the function
... Here goes the code from bb_plugins_parseMessage.code.txt...
If you still doubt how to paste all codes properly, login as the customer and go to the Compiler
tool. The add-ons you have purchased, will be available in the Compiler. Check just the add-on you have doubts for, and compile it with the core, getting the package downloaded. Then you have to analyze all files, specially bb_plugins.php and see how the codes are inserted properly. Possibly, you may discover your mistake after that.
If you will still have questions, please ask.
