Hi Michael:
Sure hope you can help me here.
I've lost my copy of MOI and desperately have been trying to re-download it here with negative results. I believe that I have followed all suggestions that I have found here on the forum. I moved the file from the downloads folder to the applications folder as per your instructions but get an ERR0R - Cannot write to plist permission problems or you are on a read only file message.
I've tried to download the file many times, but now it's time to holler H E L P !!!
