Can't load VVIS/VRAD

[Zizinhu]

Pretty self explanatory title,but anyways;

All the maps that i compile in hammer appear with a message like this:
vvis launcher error: can't load vvis_dll.dll (same for vrad)
It started happening about a month ago and i literally have no idea how to fix it (I'm quite new to mapping)

Does anybody have any idea how to fix this?

(And before anyone asks: No,there are no leaks on the maps)

A lot of other mappers have had the same problem recently, but I don't believe a solution has been discovered yet. Try verifying your game files, if that doesn't work then I got nothing. Last ditch effort, you can try uninstalling and reinstalling all your Source games and Hammer.

Just as a general response to all the threads about this, the latest CSGO update said they fixed something that was making VVIS dependant on some third-party redistributable. So maybe that's what's gone wrong here too.
