bluetooth software recommended

I have a PC, running XP. I bought a Bluetooth dongle from Fry's
electronics. For some reason, you have to purchase the license key
from the Blue Soleil website in order to get rid of the 5mb limit on
file transfers. That's a real head-scratcher, there. Please, if
anyone knows of any software that is comparable to Blue Soleil that
will allow me to transfer files with bluetooth, please let me know.
thanks! If need be, i'll purchase the license, but for now, i need
something trialware, or freeware. thanks!
