This is ridiculous, I just installed the CC trial for DW and tried all the solutions here and it still crashes when i rename a folder and it tries to update files.
My site has 914 html files and nothing fancy like CSS imports or anything like that.
I've had this happen with CS5, CC 2014 and the latest CC that I installed last night as a trial.
Seriously? And you want 60 euros a month for this?
