When you close the app, if a video is left open as a source that will be the first video shown when you relaunch the app. It is assuming that if you left the project open and that source file in it, then you are coming back to continue working on it.
Can you record your screen to show this behavior and send that with the logs to the support team for further investigation? help@topazlabs.com
We will see if we can replicate this situation to figure out what is going on.
When this happens to me, I removed everything inside the “~/Documents/Topaz Video Projects” folder - this is the path on the Mac, if you’re on windows, look for something similar under Documents somewhere…
Edit: if you’re not sure, you can start renaming the “Topaz Video Projects” folder into something else, so you have the opportunity to bring it back…
