From this pic, it seems you didn't download the mpq, or didn't place it in the D2 folder. Download this. Open the zip, take the d2_patch.mpq and put it in the D2 folder. Your D2 start screen should look like this after that:
Then download this, and again, open the zip file, and copy everything into the D2 folder.
Lastly, download this, open the zip, and run "The Sin War.reg" file, and say "Yes" when asked something.
