Now My Dropbox Taskbar Icon Has Disappeared

I'm not sure exactly when, I just noticed it. I tried a restart, it didn't help. I opened my Dropbox folder, and none of the files have the green tick on them to show they're in sync. I can access them on the website though. The icon has disappeared from Notification Area Icons as well. I tried switching to Only show notifications and then back to Show icon and notifications but the message, "This notification icon is not currently active. It will be shown the next time it becomes active.", appeared. What should I do?

 

I reinstalled the app and that SEEMS to have done the trick for NOW.
