Need help with - a low-level exception occurred in adobe player (player 76) issue

I keep getting this meeage when ever I want to use my Mercury Playback Engine GPU Acceleration (CUDA) so I keep having to use the software only but since then I've been experiencing problems with playback and I have 64GB of ram and of which 58GB ram goes for Premier Pro. It just keeps lagging even on the smallest and simplest projects. Any recomendations? Cheers
