How to fix the issue?

 

Wanted to testing the EA. But when downloading the symbol data, it always says "there are no new data for a symbol".

However, the earliest data is just from Oct 15, 2014. I've modified charts to "1872000" in the "tools" --> "options".

This kind of issue looks like happening after I install TickStory. Any interrupt between tickstory and MT4?

So strange! looking forward to early help!
