Activation not working?

Why the presentation stops in the middle after 15 minutes even though I purchased a full version ?

Hi, you opened a support ticket with the same question. I answered you there as well. I think you just might have misunderstood how to activate SlideDog once you had purchased the Pro version.

Here’s a link to our FAQ that describes how you to it: https://slidedog.com/support/where-do-i-enter-my-slidedog-pro-serial-number/
