I've got a question along these lines.
I've put all my files on an external drive and was sharing that between two computers with LR 1.0.
Now I have LR 1.1 on both computers. Grabbed my external drive on the way out the door yesterday and am now away from the desktop which was accessing my external drive just fine I am getting an error that says "Lightroom must quit because catalog named Lightroom Database.lrcat is not writtable and connot be opened" using my laptop.
What in the world does this mean? I was swapping back and forth between 1.0 versions without a hitch, now it seems with 1.1 I can't use this database between two computers without doing constant exports/imports?
Am I "locked out" of these files until I get home again and do this export excercise noted above from the desktop computer that was originaly accessing these files just fine?
Thanks,
Jake
