Re: Error calling method on NPObject

Dear Andrew,

you can fix the problem by the following:
I need you to do the following:

go to Control Panel -> Java -> Inside Java go to Advanced Tab -> in
the list appeared to you double click on Java Plug-in -> Then remove
the check for the entry you see which is "enable the next generation
of java plugin" make it like the customization shown in this image

Regards,
