3DMax material editor not filling up with materials

Hi
I have had this recently, the 3DMax material editor is extremely slow at filling up with materials, taking up to 5 mins, even with an empty new scene, it was especially annoying on a large model which I hadn’t saved for 10 mins, I stopped Max in Task Manager and had to re-do the work.

BUT after doing an internet search AI stated -
it may be your connection to the VRay licence server

So I momentarily shutoff my internet connection, not expecting anything AND hey presto the mat editor filled with lightning speed ?
Tried it twice again on an empty and full scene and the same thing happened again.

Not sure if it is a Max OR Vray thing ?
I am sure the answer is out there.
thanks
Spike

There was something similar addressed in V-Ray 7, update 2, hotfix 2. What version are you using?

Thanks for the info, was using V-Ray 7, update 2, must have missed that memo.
Will install and try.
