So first I did a clean install of D2/LOD by using the Installer from my Blizzard account. After installing LOD, I ran it, patched it to the newest version and exited the game.
Then, I installed the Median XL Launcher, but every time I press PLAY, it just restarts the launcher. And THEN, on top of that I cannot run LOD anymore, it gives me an error message first, and then asks for the CD (which it didn't before).
So yeah, any ideas?
