Need Help!! T.T

Guys why can't i suddenly use my D2 Loader. Before it works perfectly fine until it became like this. When i try opening it i have to wait around 15 min for it to start then after it started the graphics is somewhat distorted. But now i can't use it anymore. whenever i try to open it it will say We have a big error.

 

I was never able to run D2Loader so I cannot help you make it work BUT if problem persists, you can use Sanboxie Control to run several D2s

 

What is that sandboxie control? Do i n eed to download it? Thanks sir. XD

 

Sandboxie - Download Sandboxie

The free version will let you open one extra D2
