The file is correct, but unfortunately FSB is not able to load it. FSB was primary designed for the forex market where the prices looks like 1.23345 or 102.34. FSB needs a decimal separator (dot in the examples).
The prices in your file are integer numbers: 2682;2731;2678;2729...
We'll add support of such files in the future versions.
For now you can try to convert by using a script in AWK.
See this link: http://forexsb.com/forum/topic/164/awk-data-converter/

You can convert your file by using this AWK script:

# AWK script
# Adds decimal points to the prices
{
    # Input file
    # -----------------
    date    = $1;
    time    = $2;
    popen   = $3;
    phigh   = $4;
    plow    = $5;
    pclose  = $6;
    volume  = $7;

    # Output file
    # ------------------
    print date ";" time ";" popen ".0;" phigh ".0;" plow ".0;" pclose ".0;" volume;
}
