I tried what you suggested above using ARD 3.2 on my Mac 10.8.5.
As I was going through the terminal command suggested in your link, they all went through fine except for...
rm -r ~/Library/Application\ Support/Remote\ Desktop/
When I tried to run that, I got a message saying that it didn't exist.
I continued through your instructions though. When I went to show contents and followed the path, the closest file I could find to what you had said was RemoteDesktoAdmin320.pkg. So I drug that to my desktop and tried to run it. When I did, at the Destination Select prompt I got an error "SU_TOTLE can't be installed on this disk NOARDTOUPDATE.
Suggestions?
Thanks,
Bill
