i run Win98SE
and i am aware of the various Win2k problems
i'm certain that it was a plug-in conflict as i extracted ALL of the plugins.zip into ePSXe's plug-ins folder
which was when the error began
once i removed all my plug-ins and added only the few i planned to use and the error disappeared =)
i remember reading about some conflict awhile ago but cannot remember which plugin it refered too
and ePSXe runs just fine on my computer, i just accidently encountered that error when trying new plugins
