What does this Tickstory error mean?

When I run "TickstoryInfoExpert.ext" of TickStory on MT4, it always says the error in the screenshot below.



What does it mean? What the root cause and how to fix?
I posted the question on TickStory forum for a few days and no response yet.
The screenshot was made today as the issue is still there.

Hi jollydragon

This thread may help out. http://tickstory.com/forum/viewtopic.php?f=4&t=65. It sounds like it may be a symbol recognition problem betwween Dukascopy data and your broker. Go the the second page of responses and see if this works for you. This may help while you wait for an official response from Tickstory. :-)

Dear Copernicus, thank you very much for the help!
