Dropbox stuck on sync or index

It has been stuck on syncing a variety of thousands of files for over a week. I have exited, uninstalled, reinstalled as administrator, reset permissions, turned off a bunch of folders on the selective sync. Nothing works to get it back to an up to date status.

There is nowhere to click fix hardlinks

I just tried the Alt H option and that shows the links but when l hit Fix permissions it just brings up a blank CMD prompt and when l click fix hardlinks it does nothing

Ok so after some time l have a pop up saying it has fixed permissions and hardlinks but nothing has changes on the notifications on the taskbar. Do l need to restart or do something else?

I just quit dropbox and went to restart it and am now getting this:

which l have had many times before too in between days when it works

I have come in again this morning with nothing happening overnight and it is still saying this:

Please help

I have just uninstalled and reinstalled Dropbox on the comp and have received that message again. I really am at a loss here 🙂
