One person in the original release of D2:ED had a problem going indoors (Can't get into any door, game exits to windows
), but other than that I don't know if anyone has reported frequent crashes changing regions before...
There are no suggestions specifically for this, but did you look at the [PC] Support FAQ - The Dragon Knight Saga
Did you try lowering the game resolution, etc, to see if that would make a difference?
You could try doing a clean install of the game and expansion, and see if that helps (though the support tool may report any corrupt or missing files, etc; don't know, I played the Xbox version).
It sounds like you have the original release of D2:ED and the separate FoV add-on. If so, there is a (large) conversion patch
to change D2:ED+FoV into DKS (after which you can get the DKS DRM free patch
). This wouldn't necessarily help with the crash problem in Aleroth, though.
Also, you would not be able to continue with your current character in DKS, but need to start a new level 35 FoV character.
