Are you calling in for technical support of the product or are you asking tax questions?
Whether technical or tax-related, you could try asking here. Most of our members are long time users of ATX, are knowledgeable, and willing to help. Even if its a technical issue, sometimes others here have run into the same or similar problem and have something for you to try, or may have a workaround.
In addition to calling technical support, as a user you also have access to the ATX official forum where you could trying posting, and there's a Facebook group called "ATX Tax Software Support Group" that you could join. That FB group is not the one linked to in our header, although you're welcome there too.
