Having trouble importing into Articles from existing Modx docs

Revo 2.2.0-rc1
Articles 1.4.0
Archivist 1.2.2
PHP 5.3.0
Apache 2.2.11


Hi all

I have an existing set of blogs I want to import into Articles, but can't get it to work.

I have in Modx:
Home
- Blogs
-- Technology
--- post 1
--- post 2
--- etc
-- Astronomy
--- post 1
--- post 2

etc

I have creates a "New Technology Blog" Articles, and using the "Import Articles" button, I set the Parent to 270 (the id of the existing tech blog), set the tags field to "tv.tvBlogTags" and click Save.

The progress bar moves 1 block then stops and nothing is imported to the new blog.

Have I missed something?

Just updated to 1.4.1 Articles but still the same!

Also, please state any errors in core/cache/logs/error.log, more detail about the posts (are they hidden, unpublished, etc), and anything else that might be pertinent.

Done (correctly, I hope!)

:)
