I use Cryptor now, but I am receiving reports of the .dll not registering, especially under Vista. I have tried the know workarounds but they have not always solved the problem. In addition, any sales or support questions that I have sent to Xitech have gone unanswered. This makes me nervous. I haven't heard anything about ver 6. I would like to continue using Cryptor, but my customers are spread out all over the country and are not all very sophisticated. I can't afford to have intermittent install problems. I would greatly appreciate learning anything you know about the coming ver 6, especially when it might be available. Thanks
