Hi Chang,

First, I think you forgot to send me excel file.
Second, It would be nice if you could send me a screen shot with your 
error, or a dump from the Protege console, where I can see what 
exception you got, or better send me both, if you can.
Third, please make sure you have followed the exact instructions that is 
on the wiki:

Also please make sure that your Excel table is well formatted. See some 
post about this at [1]

Please let me know if this helped or you need further assistance.
