I'm wondering if I should go back to that. And I don't know how

If you saved the .exe download of that older version, my experience has been that you can just install it as you would the latest version - I never had to do an uninstall first when I rolled back to an older version but YMMV. I can't upload it to Filebin because it's reading as an illegal file extension, so if someone has a suggestion as to how to share it, I'm happy to make it available - it's 443MB.
I download and keep all releases until something renders them invalid for just this reason, but IMO StreamFab should make older versions readily available when they roll out a really borked new release like this one - people shouldn't to be penalized and have pay to get back the functionality that they gave up in a previous version!
