Returning player, unable to play after most recent updates

So I am able to run the game on my new computer however I am unable to run it from my old computer which is my preferred computer for diablo 2. I have attached an image of the error I am receiving when attempting to run the game.

Following this message is the error: "Cannot load D2Ex.dll!"

I just realized there is a solution for this in the other thread. Will try that and see if it works
