That link has been expired, then is is not work now.
You can try this way to solve it:
1st: Go to the Spinnerchief software directory and find the CTDownload folder:
2nd: Open the CTDownload folder and then delete the language that shows error when you load it in the software.
Eg, I met the error when I load the English thesaurus, then I only need to delete the English language here:
3rd: Load the error thesaurus again in the software:
(In my situation, I should load the English here again.)
And then it should work now.
