Don't see any error in the logs (and no video detected there when using VapourSynth), apart from some shortcut registration warnings.

Hm... But how do I get a specific version? License manager page only provides the link for the latest version.

I've just updated SVP to the latest version and for some reason it stopped detecting any videos when playing with VapourSynth (AviSynth works fine though).
Any tips on how to fix it would be really appreciated.

SVP Manager version: 4.0.0-6
player used: potplayer
env variables via Utilities: enabled
Core for VapourSynth feature: installed

PS: Is it possible to downgrade SVP manager to previous version?
