Can't compile or run system verilog code

[Catalin Topcea]

Hello,

I'm trying to run some SV code but each time I get the error from the picture. 

Also, sometimes when I hit refresh the page is blocked on the "Loading" message and I can't do anything. 

I tried different bowsers but I got the same issues.

Is there anything I need to do?

I'm sorry. EDA Playground has been quite unreliable lately. I am trying to understand why.
