After you open it up in one of the MS editors, can you "Save as..."? If so, try saving it as a .txt file and then editting it. If that works, you can simply overwrite the original ini. Does seem a very tedious procedure but am trying for any sort of work-around until you solve the REAL problem.
There may be a setting somewhere in your Windows profile (maybe under File Types???) that places restrictions on any file with an .ini extension. If so, that is an OS issue and has nothing to do with NWN. Do a search for any file with the .ini extention on your machine that is
not related to NWN and try to edit it. What happens?
edit: btw, if it is OS-related, using a non-MS editor should solve the problem. There are loads of freeware text editors out there.
