[Entering Engwithan Digsite Arena Sub-level causes freeze]

I have the same problem as all above and I tried to build a new character, however it happened again. Some people says that this problem is related to the RAM size, and my computer only has 4 GB RAM,which just satisfied the lowest requirement of the game. Is this the reason? And hope this problem can be fixed quickly. 

 

I have 16GB of ram FYI

[Entering Engwithan Digsite Arena Sub-level causes freeze]

So I can get into the digsite but I freeze constantly in there. I also tried loading an earlier save on the world map and I freeze there also. It starts freezing from 30 seconds to 1 minute into play. Have tried lowering graphical settings.
