Is BitsDuJour on the up and up? I bought a license for Revo Unistaller from them and all I got was an email message saying to send them a request by email in order to obtain registration information. I sent the request but have received no reply. So I went back to their website and clicked the "resend registration information" button. All that I got from that was a duplicate email repeating the requirement to send them an email request for registration information. So I sent another email & they didn't answer that one either. I bought this via PayPal. I have bought lots of apps online but never before have I had this kind of foot dragging. I wonder--should I now open a dispute in PayPal's Resolution Center, or wait a few days before filing?
