Update 2
The issue I was experiencing has been satisfied by removing the 64 bit version of the program and replacing it with the 32 bit. I actually removed the 32 bit v to try the suggestion from @sketch3d_de, but the vanishing file issue reappeared once the 64 bit v was installed again, even with the adjustment to the nVidia control panel, so I quickly reversed the procedure. Additionally, each plug in that has been reinstalled thus far works perfectly now.
Thanks for the timely advice.
