Not fully exported video after pausing

Hi, I updated lastly my Topaz from 5.3.x (dont remeber exactly) to newest version and I experienced a bug in the feature that worked before.
When exporting longer videos sometimes I use “pause” option when I need to make shorter video in meantime or just want to play a game on my computer. After that, I resume processing and it goes well. In new version it appears that video after such pause/resume treatment is bugged - there is no picture from approx. the moment I have stopped it but there is audio. The length of the video is the same as the original - the picture just freezes on last frame and not moving. From the side of Topaz Video AI it looks as exported correctly, after resuming processing goes normal, GPU and CPU works fully, procentage goes up and at the end I have green “check” sign notifaction.
Additionally I have noticed also that when I click Check update nothing happens - also on older version.
Additionally, when I go to Model manager and try to download one manually I see message " Error: Could not establish connection"

I installed previous version 5.3.6 and I will see if the problem with pausing/resuming will occur here

If you can send the logs to the support team for review it will help to get the devs to look into what is going on when pausing a longer video. help@topazlabs.com
