Lightroom 3.6, Windows 7-64 8mg ram...Program shuts down for any random reason, e.g. Importing, cropping, aspect, angle etc. and I receive “A PROBLEM CAUSED THE PROGRAM TO STOP WORKING CORRECTLY, WINDOWS WILL CLOSE THE PROGRAM AND NOTIFY YOU IF A SOLUTION IS AVAILABLE”. At this point I can’t re-open LR, I receive the same message. I have opened the Lightroom files and removed the Preference file and it makes no difference, I still get the same message. I have un-installed and reinstalled and still get the same message. At this point the program will not open at all; I have a completely useless piece of software. Can anyone help!
