I am using PlugY v10, the default that comes with D2SE v2.2.0 when enabling "Use PlugY" in System Features.

Edit: Reinstalling Median XL using the installer makes my characters work again, but I still want to use PlugY and can't.

So I haven't read all ten pages of this so I apologize if this has been covered, but my Diablo 2 is now unplayable with Median XL. I first tried to install without doing the first step of getting a fresh Diablo 2, and got the message saying that d2video.mpq and D2SE.exe was corrupted, so I uninstall...
