I downloaded CC about 30 days ago and am trying to open LR for the first time and it opens and then immediately says the program has stopped working and needs to close. How do I access LR which I am paying for each month? I've tried rebooting my system after I created my adobe ID, so are there any other suggestions to help me open this software so I can finally begin editing my photos?
What OS? If you are using Windows 7, are you running service pack 1?
Failing that, as a hunch, you might need to modify the preferences file to make sure it's not using the GPU.
And for the preferences file, see here:
