Hi, I am hoping you can help me. I am using 5.0.80. Report ID 1405136881. I am having the same error as this user. I just downloaded the latest version on a Microsoft Surface Pro 7. However, It doesn't seem to recognize my password, and the link to "lost password" on the downloaded version does nothing when I click on it. I tried changing the password, thinking that I simply didn't remember it. However, the issue is the same. The password works fine online. Just not on the download. Any ideas?

Postscript: It returns no error message, just wipes the password box clean and nothing else happens. When I try syncing, it merely repeats the error to tell me I need to add my sync information.

Thanks for getting back. Here is the play by play:

1. When I open Zotero, it shows no library.
2. When I click the synch wheel, I get the red exclamation and a message window pops up to tell me I need to add my username and password into the synch preferences.
3. When I click on the “open synch preferences” link, it brings up the window to add my username and password.
4. When I add the username and password, the preferences window merely goes away. However, Zotero still does not sync, telling me I need to add in my sync preferences again. So, it’s in a loop. The problem seems to be at the authentication level.

Another point that might be related is that the links in the sync preferences window allowing you to change your password, create account, etc., appear to be inactive. Nothing happens when I click on them.

I have the same version, 5.0.80, on my standard laptop and it is working fine, even after I changed my password last night. It automatically synced to the new password without my intervention. I wonder if something got corrupted in the download of 5.0.80. Would uninstalling and re-installing make a difference?

I wish we had an ability to upload screenshots. The four points that I outlined above are exactly what I am doing. The issue seems to be under the Zotero preferences window/sync/settings window. This is the window that pops up after it fails to sync and requests that I input sync settings. In that settings window (under Data Syncing), it is asking for my username and password. When I add them and click ok, the window merely goes away as if it has accepted the inputs and takes me back to the empty library interface. However, it still does not sync, and the red exclamation point remains by the sync wheel. When I click the sync wheel again, it merely takes me back through the same process. I am certain the username and password are correct.

Is this making more sense? I'm doing my best to describe it, however this is exactly what it happening. If it helps, the latest report ID is #621591444.

You nailed it. I wasn't clicking "set up syncing". That seems to be doing it. It's syncing now. Thanks for the tip on posting a link with screenshots the next time I have an issue that I am having a hard time explaining. I will keep that in mind.
