Windows Phone Thoughts: Are You Having Problems With the "New Posts" Feature?

After we did the update of our core code two weeks ago to launch the subscriber services, we started getting reports from people who were asking why the new posts functionality wasn't working properly any more. One of these people was our own community moderator, Steven Cedrone, and it was difficult to track down because it worked fine on one computer, but not on the other. Even after deleting his PPCT cookie, it wouldn't work. The final solution for him was to turn on "Show hidden files" and delete the index.dat file - and then it started working. But this solution doesn't seem to work for everyone, so I wanted to open this up for discussion and get a feel for how many of you are having problems with this. Please vote, and add your comments if you've found the solution above to work, or if you've managed to figure out why this is happening. :-)
