yes i've had this happen to me before and have gotten these wierd freakish realms...yea re-installing didnt work for me completely...see when you click in uninstall diablo 2 lod it will uninstall it but not delete the d2 folder...I think the way i fixed it was by unistalling and deleting the d2 folder and then installing again and making the folder anew. I'm not 100% sure on this but it's worth a try if you want to get reg realms back.
