There is nothing preventing you from downloading and installing WavePad again. The question will be whether your WavePad Master's Edition registration and activation code will work with the current release of this software. We guarantee free upgrades for three months from date of purchase, and in some circumstances this can extend up to a year. You will have to send us the details of your registration and activation code (Name - Location ID - Key) anyway in order for us to generate a new Key for the code, so at the same time we can check and test the code to see if it will work with WavePad v 2.00.
We recommend that you download and install the WavePad Freeware Version from www.nch.com.au/wavepad/index.html. This will give you the basic WavePad features plus a 14-day free trial of WavePad Master's Edition features. Then, if your licence registration and activation code turns out to be valid for the current WavePad Master's Edition release, the code can be entered into the standard WavePad software that you have installed to permanently enable the features of the Master's Edition
