I was using the Lightroom5 Trial version to explore moving from Aperture, successfully for 9 days when I decided to upgrade to LightroomCC and now nothing works.
I have tried logging out of CC and logging back in (yes, I am sure I did this correctly via Preferences)
I have uninstalled Lightroom5 (then logging out of CC and back in again)
I have tried uninstalling & reinstalling Lightroom CC
I have tried uninstalling & reinstalling Adobe CC & Lightroom CC. Again.
I have tried doing all this again & restarting my computer.
I have tried renaming the SLCache folder (SLStore folder not found)
I have deleted the contents of that folder
I have tried signing out of CC and opening Lightroom directly (I was briefly asked to sign in & accept terms but the Lightroom did not follow)
Seriously. How can I get Lightroom to launch again? Trying to reach live chat through Adobe support sends me in a viscous loop that keeps resulting in the same set of instructions that does not work.
All suggestions & feedback greatly appreciated (except the comments along the lines of logging off & logging in to Creative Cloud worked for you).
Ick. Sorry, I meant vicious cycle.
"C:\ProgramData\Adobe" folder may be hidden by default. you can search for the slstore folder and then open folder location.
this didn't help me one bit, and I've tried about as many things you have just to get the CC version to work.
I resorted to finding the download for 5.7 on adobe site and going back to the older version until the issues get sorted out.
