Re: Couldn't start Dropbox error


Hello @Paul76

I greatly appreciate the full error log you offered here! 

Seems like the Dropbox folder is not traceble by the app after your OS update.

Let's start by checking if this issue could be related to the device limit of free Dropbox accounts. If you have a free account please make sure to have only 3 devices in total listed here.

If you have a paid account, or only 3 devices we can proceed with the next troubleshooting step, which would be an advanced reinstall.

No worries! This will cannot affect the files you have on the cloud. 

I really want to know how this goes and help you with anything else you might need, so keep me posted.
