Yes, I should have checked! I upgraded to OF3 from 2 to test it out in free trial not thinking it would not be in compatible with my Mac OS (Sierra).
I just tried to open OF3 and it says incompatible with current OS. So cant do anything. Yikes! How do I roll back to OF 2 or am I in pickle? I should have kept both versions but did a Replace with OF3 when asked - in too much of a hurry! Many thanks, Fiona
