Downloading patch leads me to endless loop (Diablo 2)

So I installed Diablo II 1.13 d and applied ( all files downloaded from this website ). I added the server with the .reg file and when I attempt to connect to server I see a window saying DOWNLOADING PATCH. When it's 100% complete it closes Diablo II and installs the patch (don't know why this happens - I already got 1.13 d installed), but anyway when patching is done I just see a message saying: This patch does not need to be applied to the game. The version of the game you have installed is more up to date tha this patch.

Filename: D:\Game\D2LoD\Game.exe
File version: 1.0.13.64
Patch version: 1.0.13.64

I have tried completely remove all installed Diablo's and clean everything from the regedit, then installing a fresh one, but the same problem occured. Help, please!
