A: Please refer to our Upgrades page to check your version numbers against our shipping version. Upgrades are identical to new software except for the price. They can be installed on a new machine or on top of an old version of the program. If you have purchased an older version of one of our programs, you are eligible to buy an upgrade, and you can do so by calling our order line, or by ordering from the Upgrades section (NOT SOFTWARE) of our secure online order form. Please note: If you try to buy an upgrade when you haven't previously purchased the program, none of your order can be processed.
