D2 LOD - Reinstalled game on reformatted PC but can't connect to battl.net

D2 LOD battle.net was working perfectly fine a week ago, but I had to reformat my pc and now that I installed D2 LOD, it gets stuck on checking version and then goes to Battle.net is not responding. I literally haven’t played since I last played successfully a week ago and am not sure why I can’t log in now.

When I reformatted my pc I only reformatted my C: drive whereas D2 LOD was installed on D: drive, so I still had to delete the d2 files on my D: drive before reinstalling, but now that everything is installed, and updated to the latest patch 1.14D, it’s not connecting the Battle.net for the above reason. Please help.
