Solved My friend has an issue joining the game.

Okay, straight to the point.
My friend can't join the battlenet realm.
What I know is:
-He has Window 64-Bit
-He installed the patch properly because he could join my game via hamachi without any problems
-He can start multiplayer/singleplayer games, it just crashes when he hits "Battle Net"
-Loader doesn't work, pops with message "We have a big error"
-Windowed mode, compatibility mode etc. doesn't work and shouldn't be an issue because he can play elsewhere than the battle net.

 

I don't have the answer however there have been several similar threads in this help forum. Perhaps one of them has your solution.

 

Nope, we have tried literally everything we found on these forums.

 

Do a reinstall of d2 make sure you update it to 1.13c once installed go to website and download the zip file which has all you need inside overwrite the patch so you have out custom then make sure your using the eurobattle loader which is inside the folder you downloaded that should work and if you have gateway editor already make sure you have this info
Name EuropeBattle.Net
Zone 0
Ip d2.europebattle.net

You should be good to go sometimes if you had other mods in your folder or been using other problem can mess up your diablo 2 folder give it a try let me know good luck

 

It doesn't work.
We have reinstalled it 4 times, hell... I even packed my Diablo and uploaded it for him - same issue.

 

Are you using diablo expansion too not just the original cant see the problem maybe get new pc and reinstall ha
