If this information is omitted it will delay resolution of your question, because you will be asked to provide this information. Tech support requires a description of your computer and associated equipment setup. System details are only associated with a particular user on a per-incident basis, because we've found that users can change their systems frequently. Even if you have given this information before, please include system information in your email.

Your email and other contact information will be used only to respond to and provide answers to your questions, and not for sending unwanted spam or marketing messages, nor will they be disclosed to other parties. If you provide a telephone number in your email inquiry, we may, at our option, choose to respond with "live" telephone technical support.

We may decline to respond to inquiries from anonymous email accounts; please use your primary email address (provided by your ISP) for sending communications.

Unlike many other software developers, we provide free (we will call you upon request, given a telephone number in your email) telephone support for licensed users of our products. We have been at the receiving end of "unobtainable" customer support ourselves. For anyone that's experienced the frustration of waiting for a never arriving or a robotic, uninformative email response to questions, we continue to provide the "old school" standard of true customer support (having been in business for over 20 years).
