Hi, rubygirl.
I understand from my friend that JavaCool was able to replicate the problem. That said, since each situation is different, I suggest you email JavaCool, explaining your issue and provide a link to your topic here. You can email him at bugreports AT brightfort DOT com. Be sure to indicate in the email that you are using a Windows 8.1 NextBook tablet and getting Errors 384 and 91 on version 5.2 of SpywareBlaster.
