I keep getting an error saying service loader quit unexpectedly what do I do to correct this?

Are you running anti virus software? If so, which one?
There are a few that have been blocking the plugin.

Vanelan : So I have avast now and when I tried playing vizzed after I installed the antivirus and ran a full scan it seems to work except when I try full screen in mednafen it then crashes with just a black screen. I then uninstalled the RGR plugin and reinstalled it and while it was installing I got the message zj270 user did but the installation was successful it said afterwards. I then tried playing a game again in full screen and got the same result a black screen. I also did not do a RGR plugin complete uninstall I kept my settings but to make the plugin work I am willing to do a complete uninstall. Please help. Thanks.

hitman13 : Your monitor might not support the resolution the emulator runs full screen in.

What games have you tried to play in full screen?

Vanelan : Monitor not the problem been using this one since 2008 and been playing games on vizzed since 3 years ago never had a problem with full screen until the new latest RGR plugin version update. Remember when I told you I ditched AVG antivirus for norton well the emulator was working perfect a few days ago on norton full screen and everything but only on the chrome browser firefox crashes as soon as I launch the browser couldn't even use firefox period. Now with avast everything on my computer is running smoothly again except the vizzed RGR plugin. Don't know what to do now. What about this disabling the hardware accelerator to make the plugin work on chrome is it safe to do it or will it cause problems with my computer. I ask because I get the black screen and no sound on chrome. I would try to disable the accelerator if its safe to do so.
