Planeswalker error

I don't know if this is the right place to post this, but from the community wad, every time I try to play a planeswalker, they go to the graveyard and this error appears:
[lua] [string "ELSPETH_KNIGHTERRANT_CW_174859_TITLE (RESOLUTION_TIME_ACTION)~0x000008fa"]:2: attempt to call global 'PLW_CreateUniqueTokenForEachPlayer' (a nil value)
[lua] [string "AJANI_VENGEANT_CW_266299_TITLE (RESOLUTION_TIME_ACTION)~0x0000094c"]:2: attempt to call global 'PLW_CreateUniqueTokenForEachPlayer' (a nil value)
[lua] [string "ELSPETH_KNIGHTERRANT_CW_174859_TITLE (RESOLUTION_TIME_ACTION)~0x000008fa"]:2: attempt to call global 'PLW_CreateUniqueTokenForEachPlayer' (a nil value)
I have a Liliana from another Wad, tried to play her as well, still went to the graveyard, though this error did'nt show up on her.
Any idea how to fix this? I have a ton of planeswalkers and can't play any.
-------------------------------
On another note, every Cabal Therapy that I have, from different wads, when played, runs the effect of discarding the card 'named' if the opponent has it, but doesn't run the effect of showing you their hand. This almost completely ruins the point of CAbal Therapy having flashback.
Don't know if any of you still roam around these forums, but would appreciate the help.
