Problem with World Map

Here's what I did, I undatted Arcanum.dat from Modules Into my folder which I called ArcanumEdit I got 4 folders called Maps, Mes, Townmap, Worldmap it had sounds and stuff also but I deleted them, know when I open ArcanumEdit on WorldMap edit it freezes up.
I was trying to edit Arcanum and add houses ect.

Help to solve this or info to why it is happening would be appreciated.

 

don't delete anything in that folder, especially if you don't know what it does. It sounds like you deleted "arcanumedit/rules"

 

It was doing before I deleted it, i figured it was to big so I made it smaller.

 

what?
