Updating my Mac Pro to 10.13.1 killed my Mac so I had to rebuild.d everything. Long story, but all is working again, except RW 7.
I expect it does not know where to find the RW prefs since I store them on a external drive in Dropbox and the names of the drive was changed.
So when I open RW now, I am festered with an open dialog box that will NOT cancel, nor will it open anything. I thought it was looking for me to point to the Prefs folder, but the clicking the open button just flashes the box and stays on the screen.
Indeed, the only way to quit is by force quitting RW.
I was going to delete RW and all its Library files, but I am not sure how to get another copy since I purchased it directly from Apple.
