It only happens to one of my chars. i can enter games with all of my others, except for my only high lvl. i can log in with it but when i enter or create a game it crashes to desktop with this error message...

"Halt

Location :, line # 1678

Expression : unrecoverable internal error 06d030d1"

anyone know what that means?. thx in advance

are y getting in and out of games quickly?
if that is not the case i suggest u let d2 rest for a while and then get on again

happens to me too when i afk even for like 5 min... been wondering this too

Being as thats a client side error you need to make sure you have the right Patch installed. Also make sure you dont have any perimeters on your Diablo2 icon that your running median Xl off of.

Re-install the program
1.) Uninstall diablo 2 and all of its componets
2.) After d2 is deleted find the your diablo 2 folder and delete it (it should still be there after the uninstall leaving old chaches)
3.) Re-install

That should fix the problem if it dont work try this method, This is more time consuming because you have to download the games.

Try reinstalling with the Digital Downloads. Here's how to do it:
1) Create and verify a new Blizzard Account, if you don't have one already:

2) After logging in, click on "Games" under My Account Controls. Or, click here:

3) Click the Add a New Game button. Or click this:
(https://www.blizzard.com/account/management/add-game.xml).
4) Enter your CD-Key and select your language, when prompted.
5) You can now download the game by clicking the Windows or Apple logos, depending on your OS.
6) Install using the Game Key shown by clicking "[View Game Key]".
