Cannot launch game, cannot post in D2R Forum

I have bought D2.

  1. I cannot launch the game, I am FAR above the minimum specs required. I have updated my graphics through NVIDIA and restarted my PC

I have an RTX 2070
AMD Ryzen 7 2700X Eight-Core Processor 3.70 GHz
16.0 GB Ram
Running Direct X 12

  1. I cannot post in the forum even though I bought the game.

  2. Where is your bug support forum for D2R?
