Big problem with battle animations

[Frenzy]

Hi, I'm new here and I don't know if this topic exists, if it exists please direct me to it. If not, please help because I'm desperate!
Ok, my problem is-I've been programming my game for about month now I could say I understand most of RPG Maker, but something happened that I just can't figure out! I get to the point of the game where fourth character joins my party(my game starts with one character and then he recruits people). Anyway, when that fourth character joins and I go into random battle the game freezes and this message appears-''event script referenced a battle animation that does not exist''. I don't know what to do! I tried almost everything, but nothing works! The funny thing is that when I choose test battle the battle goes on normaly but in the normal game it just freezes and turns off. I would really appreciate any help.Please...

Go into your Database, and check your Heroes, Class, Skill, Item, Condition, Animation, Animation 2, Battle Layout and Common Events. Make sure everything is using valid battle animations or battle characters.

Well I doubled checked everything and everything looks fine.
Also, there are couple more things to say-I placed all four members in party on the begining of the game(so now the game begins with all four characters not one) and then, when I enter random encounter it works just fine! Also, I tried placing differerent fourth member in party.I used one of those default characters with already predefined battle animations, skill etc. and it didn't work(this refers to the place in the game where fourth character should join not the begining of the game)!
It's like some kind of bug! Like I can't have four characters on that point of the game.If anyone else has some suggestion please post, I'm running out of ideas...

I solved the problem! It was some stupid item that was placed in my weapon slot! But that brings me to another problem! I'll open a new topic about this...
