cause this happened to me.
1st i asked a pre-sale question and got a quality, fast response. so i bought the software, used the same email, my card was charged but haven't heard jack from them except a confirmation from 2checkout.
the site says once cc orders are verifed as non-fraud then the download link is emailed.
i have emailed them twice about my order and received NO response.
... and no, i did not find this software deal in my junk mail folder ;)
