Thanks for your post.
Is it only happening with this particular file or is happening with other files from your GoPro? Before you try this solution, please make sure all mixes are saved correctly.
Please try this:
Stage 1. Clear the Cache:
To do this, firstly close all mixing screens and click on Tools/
Maintenance. ( see screenshot)
Then click on Remove all files. ( see screenshot)
Stage 2: Once all the files have been cleared, close down trakAxPC.
Stage 3: Start the application in default mode. Default mode loads the application in its default mode. This will load up the application like the first time you ran it.
Hold down the f8 button on your keyboard while clicking on trakax icon to boot it. A window will ask you if you would like to start the app in default mode. Click yes.
After you start it in default see if the issue continues.
I look forward to hearing from you and to see if this has resolved the issue,
