Used LR yesterday. Upgraded Yosemite last night. Upgraded LR in Creative Cloud this morning. LR will not open. Opening icon appears and then nothing like computer can't find anything. I let it run for 15 minutes because 4,000 pictures in but still nothing.

Hi Mary,

Ahh. It sounds like it was a permissions issue and your admin user account was messed up. Unfortunately, this is often a problem when updating the OS rather than doing a 'clean' install.

Greg, can you try creating a new admin user account and running Lightroom from the new admin user?
