Dreamweaver's extension manager often does a poor job of updating and deleting extensions.
when you updated the extensions, did you remove them first, then install them? Or just install over the top?
I have noticed with Dreamweaver, that I sometimes have to just start from scratch with a blank configuration, and re install all my extensions.
You could try deleting those extensions from the extension manager, then re installing them.
When done, remember to remove the .dat file you referred to earlier.
Hope that helps!
