I got the same problem, reinstalling mod doesn't help. This is a part of APP log :
ERROR: failed to find file battle/RTAG (LGP) (path: FF7/DATA/BATTLE/EFFECT/HITMARK)
ERROR: offset error: CLOUD.T04 RTAG
ERROR: could not open file CLOUD.T04
ERROR: COULD NOT LOAD TEXTURE DATA FILE CLOUD.T04
ERROR: COULD NOT LOAD TEXTURE DATA FILE CLOUD.T04
and it loops for as long as the battle lasts.
