IMPORTANT: Your upgraded license will be emailed to the email address in our database and not to the email addressed used for buying the upgrade. If the address in our database is not the correct email address, then you can still buy upgrades immediately, but you will need to update your email address so that your upgraded license can be sent to the correct email address.
Optional priority support and maintenance (PS&M) (for one and two year periods) is available. This includes priority support for technical support questions as well as guaranteed free major upgrades during the priority support and maintenance period.
To add PS&M to your order, simply choose the appropriate option on the order page to add PS&M for the desired period (one or two years). The below prices are valid only when buying new licenses or when buying version or edition upgrades for existing licenses and are in addition to the new license or upgrade price.
NOTE: New orders for (and upgrades to) the enterprise edition include one year of PS&M at no additional cost.
