SpywareGuard - how do I stop error "9" pop-up window?

Hi I have been running SpywareGuard for a few weeks without any problem. In
fact it seems to detect most things being thrown at my computer.

Yesterday I started to get apop-up box headed "SG Browser Hijacking
Protection" then a yellow triangle with an exclamation mark in it and "Run
time error '9' Subscript out of range with an OK box to click. If a click
it, click the closing x or right click and tell it to close, it closes and
then almost immediately reopens.
