Codebook manual upgrade 3.0.5 issue - can no longer sync with dropbox

Win 10 Pro, 64 bit

Just manually updated to Codebook 3.0.5 - now it will not sync with my dropbox DB. Error message attached.
My iPhone and Mac accounts work fine, as does my un-updated Windows installations (on other PC’s).

Thanks in advance for assistance!

Hello @edbuck

It appears that Dropbox may be experiencing intermittent network issues. Would you try your synchronization again in a few hours to see if the issue continues; or alternatively switch your synchronization provider to Google Drive within the File → Preferences window? Thanks!

I had the same problem Ed. I unlinked and then re-linked my account and it took care of it. After you unlink make sure you fully exit Codebook before linking again.
