Illegal exeption when Inventory button pressed (SOLVED)

[Big Nerd]

While I was testing my game, I pressed the inventory button on the GUI and the following error message appeared:
 

Illegal exception
----------
An Illegal exception 0x0000005 occured in ACWIN.EXE at EIP = 0x00472148 ; program pointer is +6, ACI version 2.72.920, gtags (45,36)

What should I do?

Are you using the default built-in inventory or a custom one? If it's the former, have you deleted any of the inventory graphics?

[Big Nerd]

I'm using a custom one. I don't now if it matters but I'm using the "Inventoryscreen ()" scripting command.

The InventoryScreen command brings up the default interface, if you've made your own GUI then you need to display that instead.

Thank's for the help. I did what you said and it worked. Thank's again CJ.
