I have the Poisoned and Numbing Poison effects on me but Waters of Life is greyed out. ( Or can't it be used at the same time as regen infusions? I played too much with undeads. )
I read that Wild Infusions at first didn't remove vine poisons in the prerelease versions, so this may be related.
Did you extract the game/modules/tome-3.9.35.team file? It should be openable like any .zip file.
Inside it you will find most files ( all but the engine files ).
