When FSB loads a data file, it tries to determine what column is High and what column is Low.
The program recognizes two formats:
1. Open High Low Close
2. Open Low High Close

To do that FSB uses the following formulas (for the first format):
High > Open + pip AND High > Close + pip AND Low < Open - pip AND Low < Close - pip

In your file (4378 lines) there is no even a single line that matches this pattern.

There is no line where High is greater then other prices and Low is lower then others.

You can easily change slightly the file in order to make it acceptable for the program.
For example the first line of the file is:

2011.02.10,02:09,1.37300,1.37400,1.37200,1.37200,1191

You see that Low is equal to Close. If you reduce Low by two point (1.37198), FSB will load the file correctly.

Corrected first line is:

2011.02.10,02:09,1.37300,1.37400,1.37198,1.37200,1191
