I'm having the same problems here. Seems like I'm missing one of the trusted versions of the game, according to the Dat-O-Matic database.
The two No-Intro versions I have:
File: NHLPA Hockey 93 (USA, Europe).md
Name: NHLPA Hockey 93 (USA, Europe) (EASN)
Alt: NHLPA Hockey '93 (UE) (REV00)
SHA1: 8EFC1CACB079EA223966DDA065C16C49E584CAC2

The version that the submission was made on seems to also be a good dump according to the No-Intro database:
Name: NHLPA Hockey 93 (USA, Europe) (EA Sports)
