Exporting to youtube problems

I have been using the free version of the activepresenter for a while now and love it. Today, I have had trouble exporting to Youtube.
I keep getting the error message
I have tried going back to previous version and then back and updating to 8 and get the same problem every time. I have also noticed recently that the timeline is much smaller than it used to be. I am curious if the can be made larger?
here is a screen shot.

ActivePresenter Version: both 7.5 and 8

OS: windows 10

Notes: I have tried starting and restarting computer.

Hi James,

Can you please share the log file of ActivePrsenter in the folder %APPDATA%\ActivePresenter?
You can send it to our support email at support@atomisystems.com
I guess it might be network or Youtube quota limit issues, so it may work if you try again at another time.
You can also export to video and upload it to Youtube manually from your web browser.

Regarding the timeline, you can right-click a timeline item and select Waveform Bar Height > Large from the context menu.
