Thanks Lee Jay.
I did open up the older LR 2.7 but it's still opening with the older version.
Could it be that I still have the older 2.7 version and the new 3.6 together in my harddrive?
Was I supposed to do something when I first installed 3.0/ 3.6???
Icould reinstall 3.0/3.6 upgrade. but I'm concerned i'll delete the work I've already done on each
