Use search button next time

Edit: you need 1.13c version of diablo, if you have a previous one,or a later one, you have to upgrade/downgrade it

I´ll reinstall it again and give it another try.

I did a clean reinstall and updated to 1.13c, i replaced the the patch data with the Median Xl patch data and started the TSW2.reg. and it still does not work, did i something wrong?

how did you update it to 1.13c?

did you choose the sin war server to connect, not the battle.net?

moved to the sin war subsection

I searched for a patch to 1.13c in the internet and installed it. and i selected TSW2 as the Gateway.

I assume you used the XIV-b MXL: Ultimative version?

I downloaded this one: http://www.moddb.com/mods/median-xl-ultimative/downloads/median-xl-ultimative-xivb
This is the right one?

DId you run in winXPsp3 MODE?!

Do SO!

(sounds kooky but win7 mode will work in win8 and win8 works naturally) this has 50/50 chance of solving. I don't know why though!

Win7 unless you use D2SE prog will NOT work using the methods above. sucks don't it?
