So hopefully this will help out others, Go to your 64 bit client, right click it and go to properties, Go to compatibility and run it as windows 7. This helped me.. My pc specs are the follow: Windows 10, GTX 970m, i7 5700hq, 16 gb ram.
Hope this helps other people, I had the purple textures before, tried compatibility and all the textures that were missing, were fixed upon using this method.
Also if anyone else has missed my other posting about the Fix for the FPS loss in the 64 bit client(8-10fps etc) That thread is:

Please leave some feedback if it worked for you or not. Thanks
