twitter tools

i have read the blog posting and still cannot get the latest ver of TT to work (2.21) as of 4/1/10. I am using WordPress 2.8.6.

my tweets http://twitter.com/DGWA will not post to my WP blog here: (last tweet update Jan 2010) http://www.davidgratke.com/blog/

I think this quit working when i ‘upgraded’ from WP 2.7xx to 2.8xx
