Ok, i found a few problems.


First problem is you are using SetTimer, instead of SetTimerEx, so you dont pass its playerid.
This brings up the problem that you need to store a players 'TimerID'

At the top:

pawn Код:

new playerTimers[MAX_PLAYERS];

Setting the timer:

pawn Код:

playerTimers[playerid] = SetTimerEx("AutoCrack", 3500, true, i, playerid);

Finaly, Kill this timer when they Die, or disconnect:

pawn Код:

public OnPlayerDisconnect(playerid, reason) {
    KillTimer(playerTimers[playerid]);
    return 1;
}
public OnPlayerDeath(playerid, killerid, reason) {
    KillTimer(playerTimers[playerid]);
    return 1;
}

About the commands, '/crackme' is 8 long, so:

pawn Код:

if (strcmp("/crackme", cmdtext, true, 6) == 0)

Should be:

pawn Код:

if (strcmp("/crackme", cmdtext, true, 8) == 0)

I hope this helps.
