Technical support is available by calling 415-483-8000.
Technical Support will work closely with you to solve any problems related to our software. Please give our support technicians as much information as possible. Remember that they are not in front of your computer and that they need your help to diagnose the problem.
On occasion, a problem can be traced to hardware, or to another software application. Our technician will supply as much support as possible in these cases, but they are not authorized to support products manufactured or published by another company.
You might find that e-mail is a more convenient way to get technical support. If you do send e-mail, provide as much information as you can about your system and about the problem.
