Sorry for the very late reply, I've been extremely busy lately.

I've just tested the command with 10 seconds, and it seems to work perfectly.

Thank you !

Hello, SteaG.

Thank you for your support.  I want to make sure we fix the correct issue..

Tell me if you are signed in to Google, and have it syncing your Chrome bookmarks to other devices.  If you're not sure,

• Launch Google Chrome.
• Click in the menu: Chrome > Preferences
• In the left side bar, click Settings.
• Does it indicate that you are "signed in" to Google?
• If so, click the Advanced sync settings button.
• Is the Bookmarks checkbox switched on?

Indeed, if you are syncing bookmarks with Google's Sign In, BookMacster must launch Chrome if it is not running, prior to any export.  If it turns out that you are, please do this

• Quit Google Chrome if it is running.
• Launch BookMacster and open your document.
• Update a bookmark somehow.  Maybe rename it or move it a little.
• Click in the menu: File > Export.

BookMacster will launch Chrome, wait 10  6 [corrected 2013-12-15] seconds, then try to export.  If I understand the problem correctly, this should evoke the same error that you see during syncs.  When you see it, click the button in the lower left corner that has the life-preserver icon in it.  It will create an email message to us, containing much data about the error.  Add the answers I asked for above and send to us.

Again assuming I'm correct about what's going on, there are several other ways, besides exporting manually after launching Chrome.  One is, if you are not syncing to Chrome on other devices, either sign out, or at least switch off that Advanced sync settings > Bookmarks checkbox.  Other workarounds are explained in this section from BookMacster Help.

I wish Google provided a way for us to get in to Chrome's bookmarks in the cloud without through the Chrome browser app.  Unfortunately, the Chrome team has been following Apple's lead lately and walling things off.
