First - reboot your Indigo server Mac and see if that doesn't clear it up.
If not, it may be that you've got some permissions that have gotten munged - try this:
1) Launch the Terminal application (inside /Applications/Utilities/)
2) Copy/paste the following lines into Terminal. You will be prompted for your OS X admin account password after the second line, which needs to be entered so that all the steps complete successfully:
3) Copy/paste each line below *individually* and hit the return key after each one:
cd /Library/Application\ Support/Perceptive\ Automation/
cd Indigo\ 4/Preferences/PrismReflector
chmod ugo-x *
chmod o-rwx *
chmod g-rw id_rsa
4) Select all and Copy/Paste the entire contents of the Terminal window into a reply for me.
Here is what I got.. I ran the stuff you told me as you told me, or at least how I interpreted you wanted me to do it. I copied and pasted the first two lines of instructions as ONE command, as you have it written, and then hit RETURN. I did this several times but only ONCE did I get a prompt for my password... I then copied and pasted EACH line separately and hit return .....below I have pasted what I got back from THAT time. Hope it makes sense to you cause it means nothing to me....
