Timbuktu Problem with text

I am working on a script that will reply to Timbuktu Flashnotes confirming an action has happened. I wrote a proof of concept script to get this working, which is below.
The problem is that even though I cut and pasted the exact code into my larger script, every time it goes to set the text of the I get this error:

Timbuktu Pro got an error: Can’t set every text of outgoing flashnote id 2665 to “test13.1mgs.mov UPLOADED 13.06 Mb in 16 seconds”.-10006

Here is the small script, you need to have just one flashnote open for it to work. (I check for it in the larger script).

set log_entry to “test13.1mgs.mov UPLOADED 13.06 Mb in 25 seconds”
tell application “Timbuktu Pro”
activate
set fromAddress to address of window 1
set OutNote to make new outgoing flashnote connecting to fromAddress connecting as guest
set text of OutNote to log_entry
properties of OutNote
–send OutNote

end tell

In the real script, the log_entry is built with this command:
set log_entry to name of item_info & " UPLOADED " & uploadedMegs & " Mb in " & uploadTime & " seconds"

Thanks for any help.
