I have made a hack for diablo 2, Im crashing in the game please help

[BeginerHere]

I have made this code. And I seem to be crashing in the game. Here is the codes I used. Do you maybe know why Im crashing?

if (Packet[0] == 0x4C && Packet[1] == UNIT_TYPE_PLAYER)
  {
   LPUNITANY pUnit = GetUnit(*(LPDWORD)&Packet[2], UNIT_TYPE_PLAYER);

     if (!pUnit)
     return TRUE;

   D2SpellInfo Spell;
   GetSkillInfo(*(LPDWORD)&Packet[6], &Spell);

   //Print(0, 5, "%s casted level ÿc3%d ÿc5%s", pUnit->pPlayerData->szName, Packet[8], Spell.szSpellName);

   if (*(LPDWORD)&Packet[10] == Me->dwUnitId && !InTown(Me) && V_TPWhenAttacked)
   {
     if (Spell.dwSpellInfoFlag & DSI_PARTYCAST)
      return TRUE;

     LPROSTERUNIT pRoster = FindPartyById(pUnit->dwUnitId);

     if (!pRoster)
      return TRUE;

     DWORD dwFlags = GetPvPFlags(pRoster->dwUnitId);

     if (dwFlags & PVP_HOSTILED_BY_YOU || dwFlags & PVP_HOSTILED_YOU)
     {
      Print(0, 4, "ÿc5Escape: ÿc-1%s attacked you", pRoster->szName);

      if (Portal())
        V_TP = TRUE;
      else
        ExitGame();
     }
   }

   return TRUE;
  }

  if (Packet[0] == 0x4D && Packet[1] == UNIT_TYPE_PLAYER)
  {
   LPUNITANY pUnit = GetUnit(*(LPDWORD)&Packet[2], UNIT_TYPE_PLAYER);

   if (!pUnit)
     return TRUE;

   D2SpellInfo Spell;
   GetSkillInfo(*(LPWORD)&Packet[6], &Spell);

   Print(0, 5, "%s casted level ÿc3%d ÿc5%s", pUnit->pPlayerData->szName, Packet[10], Spell.szSpellName);

   return TRUE;
  }

Well Bascially I dont crash until The hack prints something on the screen.

I don't have much experience with packets, maybe someone like Konsowa can give you some insight on this.

Well check if spell is casted if u don't print anything

Well basically. What this does is reads and prints what every charater in the game is casting. And what level it is.

If nothing is casted. Nor printed onthe screen. I dont crash

Well the packets it self prints into the game. I have attached my packets.cpp to this post.
It doesnt use the chat functions when it prints

Its Packet 0x4C & 0x4D

A few things can be wrong:

1) Offsets
2) Structures (i dont see the full code, but every code is build on them)
3) Did you included the right libs?

What you can try is get OllyDBG & Reclass and start reversing all the stuff again, it might be a bit of work but if the hack is that impotent it will payout
