The PC Quilter itself is upgradeable. I have had to do that to mine. It has not cost me extra to do that. I do know you have to do somethings to transfer ownership from one person to another. I would check if it uses a serial port or UBS. I had to change mine to a UBS because of issues with the serial port. Support now costs $75 for 6 months. It is only available 3 days a week I think. Melonie is very knowledgeable and easy to work with. You do need some computer savy. I am using a old computer because I am to lazy to update it (some have had issues when going to a newer operating system). There is a learning curve. I am not an expert by any measure but I am glad I have it.
