Help with two TMNT chars

[Orange]

  Wazzup everybody. Whenever I try to play as Donatello by Erradicator and Leonardo by ByteZero, these problems pop up:

For Leonardo:

Assert failure in array.h line 110

For Donatello:

Error message: Can't load don.air
Error loading chars/donatello/donatello.def
Error loading p1

Library error message: Error in clsn1 in [Begin Action 305] elem 0
Anim error reading chars/donatello/don.air

Does anyone know how to fix them?
