The FAQ page says, "If you choose not to purchase the WavePad Master's Edition licence upgrade at the end of the free trial period, the advanced features will be disabled but the standard WavePad features will continue to work."
My free trial period has ended, and I receive an invitation to pay for the Master's Edition, but I want to just continue to use the standard WavePad features for free. I clicked No to the invitation, I clicked Cancel, etc. I cannot open WavePad to use it. I am always sent to the webpage to purchase it. Any suggestions?
