Sorry for taking a while to respond, I deleted the entry for ELE and I ran Worlds.pas BEFORE you edited your response (so I have not downloaded the new version of ELE, as you said deleting the problematic entry should be harmless I have not bothered) without great errors (although at first it gave me an error about not enough parameters? It works fine now though for some reason) HOWEVER, it now says this: "LODGen.exe still seems to be running. Giving up waiting for it. DynDOLOD Worlds completed successfully." It took less than an hour to complete (I have a very good computer), so I am basically asking if this error needs correction or whether I am good to go and play the game. Once again, thank you very much for your timely and detailed responses and continued willingness to help and fix problems. I again thank you greatly for any further help you may give me.
