Ok here is what I had to do to clear up the timing error when opening Gangnam Style.
1. Open .lms file with notepad
2. Go to the bottom and look for the line that talks about track length <track totalCentiseconds="0">
3. Change "0" to "21900" (21900) is the length of the mp3 I had 3:39 seconds converted to centeseconds 219 seconds X 100 = 21900 centiseconds.
4. Now click save as and make sure you save it as all files instead of txt which is the default, and leave encoding at utf8
5. Name the file anything you want and add the .lms at the end.
6. Click save and open in LOR.
PM if you have any questions
