How do I fix an unhandled exception in my dll?

Im writing an aimbot for a game called assault cube and I have written a function to grab all of the players in the game. Im currently trying to get the team of the player that my function gets, but for some weird reason I get an error. The Error: Unhandled exception at 0x08ED66D0 (finalaimbot.dll) in ac_client.exe: 0xC0000005: Access violation reading location 0x000003CA.

This is really weird because the address im reading from is way higher than 0x3CA.
