Our class has a license for CS3 Web Premium. It was obtained years ago. In fact the original teacher no longer works here. I need to install the software on a new computer. I tried to deactivate it on the old computer, but there was not an option to deactivate it. So, I simply uninstalled it. I reinstalled it on the new computer, but when I enter the serial number it says maximum number of activations reached. Please help! How can I get the serial number deactivated so that I can install the software on new machines? Thank you.
