I have upgraded my computer and need to reinstall Stitchmastery. How do I do that?

You can download a copy of the software from our Downloads page.

To activate the software, you can reuse your Activation Key. The activation key is valid for a limited number of activations. If the software fails to activate then this is likely because all of the activations have been used. Contact [e-mail] with details of your Activation Key and/or purchase details so that the number of activations for your key can be increased.

Bear in mind that the new copy of the software will not include any user stitch libraries or stylesheets you've created - those are saved locally on your own machine. You will need to transfer these to your new computer yourself, either by saving them to a pen drive / external hard drive / cloud-based storage eg Dropbox or Google Drive, or by emailing them to yourself (either directly or using a service such as www.wetransfer.com)
