Aarghhh! Thanks so much for letting me know. I don't know how that happened, I was sure I packaged it correctly. I've uploaded a corrected package and versionied it 2-2-6-7-c. I'm surprised no-one else has posted about problems with those features.
For anyone using 2-2-6-b MS SQL files, the only difference in the new package is the following files from the bin folder:
So if you are alreeady running MS SQL version 2-2-6-7-b, you only need to upload those files and touch your Web.config to recycle the app.
Again, thanks for letting me know Rob. Hope you are doing well!
