Jia,
We have a 30-day money back guarantee. If you'd like to take advantage of that, please use the Refund Request link at the bottom of every page of this site.
If you just bought on Friday, you have plenty of time to request a refund. I just responded to
your other post
about the com_com_jfbconnect issue and I believe we're on the right track. Please try the suggestions there and let us know if you need anything else.
Thanks,
Alex
