After the first few days of using the trial version of LR on a brand new computer, it suddenly won't open. It just says "not responding". Any ideas?
Which version of Lightroom is it and what is your Operating system?
Make sure your Graphics card is up to date.
If it is Lightroom 6/CC Refer this to manully disable use of Graphics card usage in LightroomLightroom CC freezes when on Develop mode
