Has there been any progress on a finding out why this happens and how to permanently fix this issue?
This work around is not a solution as it seems to revert back to it's evil ways the next time I want to use DA. It's a long and frustrating process and I'm wondering because if you can't fix it in DA2 then I can only assume this issue will be in DA3 as well.
Users who ran into this issue in the past got it working by Deleting the Configuration folder and reinstalling the extension.
To do that, please browse to your Dreamweaver Configuration folder (You can find your configuration folder by looking in the following pdf common_installation_issues.pdf) and rename the configuration folder to Configuration_old.
Open the extension manger and remove all extensions and then install only DataAssist. Open Dreamweaver and try it again. If you still get the error please let me know.
