unknown version error

hello i just downloaded the oblivion realm installer and followed the steps untill i try to launch the loader that appears at desktop and it says this: d2loader does not recognize this version of diablo 2. This build is only designed to work with diablo 2 ¿¿v1.12?? why say this i though this server requires to have 1.13c version wich is the one i got i have the original game with cd keys

 

It is right that this server works best with 1.13c.

Have you tried to connect as it's described by the MANUAL Connect guide?

lol im dumb the launcher that appears after installing oblivion realm is not the one i have to start xd it was the old launcher

 

What I would recommend here is to reinstall Diablo 2 LoD (should be v. 1.12 then), install Oblivian Realm patch afterwards and then patch Diablo 2 LoD to 1.13c.
