On starting LR this error changing modules - on Mac OS 10.10.1 - I have removed my NIK software, trashed the adobe LR preferences and done complete new install. If I have to change user accounts to get it to work it won't be worth having.
The bug prevents me from changing preferences or using LR

Looked for your answer to my "LR this error changing modules - on Mac OS 10.10." question in Photoshop GF and didn't find it. I'm getting the feeling that the easiest thing is to delete all evidence of adobe PS and Creative Commons from my system and reload. Am I on the right track? By the way, LR works fine on my laptop with the same OS.
My apologies Veronagent I moved this discussion to the Photoshop Lightroom forum.
