These instructions are no longer relevant; the format of the FH+ download is now an install program instead of a .zip file. I'll update this thread as soon as I have time, sorry for any inconvenience!!
@rockinval93 - No, don't delete your old version. Make sure you haven't replaced any of the original FH files with files from FH+. When you open up FH+, go to options, video, and switch the rendering subsystem. That should fix the black background deal. Once you get on a char and go ingame, if your screen is black except for your char and the chat/icons, press B and reset your home to Bonfire, then go home. If you have any more questions, feel free to PM me!
