Emulator Problem: Pete's plugins missing render-texture extension!

Hey, I'm trying to use Pete's open GL2 plugin for espxe 1.7, but every time I try to run a game, a notice pops up saying "Missing render-texture extension" and "No pixel format available." I have already tried re-downloading the plug-in from his site, but to no avail! I would use my other plug-ins, but I need that fake low compatibility frameread in this version to fix my game transitions

You have a graphics card older than GeForce FX or Radeon 9500 is my guess. Disable Pixel Shader in options or switch your plugin to Pete's OpenGL 1.75(6).
