Most GTA installation files are set as read-only. You will need to right-click on your GTA folder and uncheck the read-only attribute. Also ensure that you select propogate to all child files and folders.
Another problem is that the program is still in a very early stage and you are attempting to move binary IPL files instances (When you select an object, it should say Binary IPL file editing is disabled if the item is binary), you can easily add new objects or copy and paste etc. Don't worry, I do intend to allow you to do this, I just need to get my image archiver working correctly first.
Yo so i went and right clicked my gta main folder in the rockstar directory then went to properties and set as a non-read only, then it propted me with this folder or all sub folders so i chose all, sure enough i went in the map editor moved somethings, saved, loaded SA and guess what...........BOOM it worked.
I gotta say thanks man you are amazing. how often does a program come out and have some problem and you ask a question and only get NO answer or NO solution.
