Have used Lightroom (various versions) for 2 years. Upgraded a few weeks ago to Lightroom 6 on my desktop pc running Windows 7. No problems initially. However 2 days ago, it started to refuse to open and despite constant attempts, including rebooting, it is not working. When I click to open, the initial screen (with trees) opens, then nothing. When I click on the menu bar, it freezes, screen greys out and windows message to tell me 'LR not responding'. I then have ot Ctrl/Alt/Del to close.............................. and so on.
Very frustrated. I have tried the online tech help desk without any success (am on to them as I type) but am told there is no one competent to help!
Any proposals other than detailed programme changes as I am photographer and not a software engineer.
Since I reported the above, a helpful chap in Adobe Support accessed my pc on line and tweaked something including the update just announced for LR6. It appears to be working (fingers crossed).
