Getting dialog saying can't start dropbox.

This just started happening today.

Thank you.

OK - I figured it out.

I had 2 sessions of Remote Desktop connected to the same user account.

Seems like 2 instances of Dropbox were fighting over the Dropbox database resulting in Dropbox not being able to start up.

Solution - log out of both Remote Desktop sessions and then log in with a single session.

Hi there! It looks like Dropbox is reporting an Operational disk I/O error. This means that Dropbox can't read from your hard drive. It is usually indicative of an underlying hardware issue.

I would highly recommend that you have your hard drive backed up and checked by a professional. You can learn how to check your hard disk for errors here:

WINDOWS:

http://windows.microsoft.com/en-US/windows-vista/Check-your-hard-disk-for-errors

MAC OS X:

http://support.apple.com/kb/ht1782

Note: it can take a long time to check your entire hard drive.

Hope this helps. Happy Dropboxing:)

My dropbox install install on ubuntu 12.0.4 somehow stopped functioning, so I have tried removing and reinstalling, but now I get this error despite setting permissions correctly.

Can someone tell me how to fix this? I can access Dropbox online, but not on my Mac. It closes right after I try to open it up with an error that says "Couldn't start Dropbox. This is usually because of a permissions error. Storing your home folder on a network share can also cause an error."  In the Advance section at the end of all of the coding, it has "OperationalError: user-defined function raised exception" Please help!

Thank you!
