I have LR6 - the offline version that I purchased in 2015 as my work requires me often to be offline ... I am on Win 10 on Surface Pro. About a month ago, LR6 stated working slow .... then a few minutes ago, it was slow again so I rebooted ... and now LR just keeps looking at me and saying that it is not responding!! ... That is not funny at all as I use LR for work. Can you please help urgently please? Thanks.
