MDB Error "Invalid Token"

I need some help. I have just implemented MDB postprocessing and I'm not 100% confident but it seems to be working until it gets to a certain program. When I look at the program in the grabbed data it looks like this:

  </programme>
  <programme start="20151103033500 +1100" stop="20151103042000 +1100" channel="FOX8">
    <title lang="en">The Amazing Race</title>
    <sub-title lang="en">Amazing 'crazy' Race Part 2</sub-title>
    <desc lang="en">Amazing 'crazy' Race Part 2: The final three teams sprint to the finish line in Alaska for the one million dollar prize. The final three teams sprint to the finish line in Alaska for the one million dollar prize</desc>
    <date>2013</date>

    <episode-num system="xmltv_ns">22.11.</episode-num>
    <rating system="ACB">
      <value>PG</value>
    </rating>
  </programme>

In the log file the messages are as follows:

Anyway, I'm stumped! I have attached the appropriate files if anyone can help. Thanks in advance.
