Spyware Blaster crashes Kernel32.dll

I've been running SpywareBlaster for a while, and really haven't had any problems with it. But in the past few days, it's started crashing. My Dr. Watson log is as follows:
Win32 Kernel core component attempted to use a null data pointer variable.

Module Name: KERNEL32.DLL
Description: Win32 Kernel core component
Version: 4.90.3000
Product: Microsoft(R) Windows(R) Millennium Operating System
Manufacturer: Microsoft Corporation

Application Name: Spywareblaster.exe
Description: SpywareBlaster
Version: 3.04
Product: SpywareBlaster

I'm also runing AVG 7.0, ZoneAlarm 6.0, Windows ME and IE 6.

Any help would be appreciated.
