downloaded project 64 last night with a few games. i cant figure out the deal with the plugins. error message reads: graphics plugin missing or invalid, go to settings and choose a plugin. i went to settings, and there is nothing to choose from in the video, sound, or controller sections, they are all empty. so i found a graphics plug in glN64_v0.4.1 but i cant figure out how to use it. its a zipped file, still wont let me open with project, keeps repeating the error message. i have windows vista home premium if that helps, and ive already checked for windows updates
