I just downloaded dropbox from their site. It is installing. It has reached the point of creating the dropbox folder -- if this was a new install. However, this is a reinstall.
"Couldn't rename Dropbox to make room for your Dropbox folder.
Dropbox needs to rename your existing folder or file named Dropbox to finish installing. Please close any open documents and try again."
I have no files open that I can see. Should I reboot?
