There was a message thread the other day about an error message some of us were getting when exporting from LR CC. It turned out the problem had to so with Bridge being open at the same time LR was trying to export from the same folder Bridge was pointing to. After closing Bridge, the LR export problem went away.
I have no idea if your issue is related to Bridge being open at the same time you are importing to LR, but I thought I'd mention it since you mentioned Bridge.
This error message means the Destination directory, where your photos are to be copied into, does not have write permission. Change the permissions on that exact dir to Write.
I installed Bridge after the issue for the main reason was to see if there might be an problem with the CF card
That was it
