I had this problem when I first tried out my !points command. Your Point.ini file should be located in the mIRC folder.

C:/Users/YOURUSERNAME/AppData/Roaming/mIRC

I manually created the Points file, and had to change the extension from .txt to .ini and drag it to where it needed to be. After that, it worked perfectly.

But if that's where the file is located already, then it might be a problem with the code. Though I doubt it. If that doesn't work, let us know.
