Scripting "start downloads"

I want to write a script that will take the list of files to download in the “download manager” and actually download them. I see in the Devonthink Pro applescript library the following command:

start downloads v : Start queue of download manager.
start downloads
→ boolean

So to try this out, I’ve written a basic script, but it won’t compile:

tell application “DEVONthink Pro”
start downloads
end tell

What am I missing?

The boolean part. In case you didn’t know that’s a true or false. This is a required parameter (or else it’d be in brackets like [position] or [type] or [whatever] as an optional parameter).

start downloads true

Thanks, but I had already tried that (should have been clear in my first message). Getting the same “Expected end of line but found identifier.” error even with true (or false).

UPDATE: It’s odd, but by restarting the Applescript editor the problem went away.
