Custom commands/packets on windows 7

[jewness12]

Whenever my players in the server use a custom command that sends a packet to the server they crash.
This happens ONLY on windows 7~
works perfectly fine for XP users.

How the hell can I fix that?

Check for DEP with GetSystemDEPPolicy() on the player's PC; it usually is the cause of client crashes.

Tested on a win7 player, I used GetSystemDEPPolicy and the return code was 2.

OptIn (2) On systems with processors that are capable of hardware-enforced DEP, DEP is automatically enabled only for operating system components. This is the default setting for client versions of Windows. DEP can be explicitly enabled for selected applications or the current process.

He still crashes when he uses the commands

== edit ==
turned DEP to AlwaysOff (0), still crashes.
