The error seems to start coming up here:

004AC5CA |. E8 9168FEFF CALL SystemCl.00492E60

Not the first time you get here, but if you trace into this call, eventually you get to here:

0057F991 FF92 EC000000 CALL DWORD PTR DS:[EDX+EC]

Which leads back to the first mentioned call, and then the error message opens.
