GPS Data Logger Software - BT747

I have a Holux-241 and a Macbook Pro running OS10.7

Holux's utility software doesn't work, so I downloaded and installed bt747. I also installed the USB driver for the 241 off the Holux site. 

Being technologically non-proficient, I got this far before hitting a wall. Are there step-by-step instructions on getting this thing to operate somewhere? Does anyone have suggestions or tips? Any help would be MUCH appreciated!

Cheers!
