I added projects, and when tasks completed, I updated the project and those tasks disappeared but work done still shows 0. Whats happening? Is my computer even doing anything?

A search of the stats would suggest that, among other things, you're not using the username "prasant94" at the projects... Since you don't seem to be using the account manager either (which would generate new accounts with your BAM username) you should do a search of whatever your other username is using the box in the upper-left of this page.

Wow, there seem to be a lot of posts about very basic problems lately. Perhaps the documentation is in need of some updating, and a more prominent place on the website?
