Turn of anti alias (ClientLoader) and ansi tropic filtering (ClientLoader and Drivers). Turn off AlphaBlending (PEAss). Turn off Advanced Input something something (PEAss).
Uninstall PEAss and delete all files in %entropia% starting with PEAss, including the PEAss folder, then reinstall. Be sure to use full screen mode to test if it works, before you try windowed mode.
If it still doesn't work then, it just wont work. Sadly this is the case for some people.
