OpenGL & GPU Gems 1 Fast Fluid Simulation

I am a beginner at using OpenGL and I am researching fluid flows. I want to use the GPU Gems 1 Fast Fluid Simulation as an example in my research but I am having trouble getting the simulation to run. The program is throwing an exception at the multitexturing function (glMultiTexCoord2f) of the Slab Operation class.

“Exception thrown at 0x00000000 in flo.exe: 0xC0000005: Access violation executing location 0x00000000.”

Also, the pc I am working on has two gtx 1070 cards. Can anyone point in the direction of what the issue could be? Any help is appreciated. Thanks in advance.
