I have been having some issues with Aali's custom driver and FF7 remix.

I'm new to the forum and Ive been trying to find info about this issue on the internet but have been unsuccessful.
First I installed FF7 and the 1.02 patch, then remix (not realising that it already contained said patch) and it worked perfectly for a few days (and was awesome!). Then I decided to try playing around with some of the settings in the opengl config file. Being a newbie and not really knowing what i was doing I followed a tutorial i found on youtube (
) after applying the changes I began to get an error message during battle: "GLITCH: Something tried to use hardware accelerated lighting, expect funky-looking models" (I've gathered that this may have something to do with Aeris having just joined my party but at the time I assumed it was because of the changes I had made. Now I'm not sure. :-\)
Changing the settings back in the config file did not solve the problem so i completely uninstalled the game and deleted all the mod files, then reinstalled everything over again and started the game and... black screen... "ff7.exe has stopped working"
I've repeated this process many times over the past few days and all I know is that the game will run fine with the 1.02 patch only, but if I try to use remix or Aali's driver it won't even start up.
I apologize if this is a question that has been answered already but all of my searches have been fruitless, so if it has been answered, at the very least can someone point me in the right direction?
thanks in advance.
