Probably your preferences were reset. I don't know why you aren't seeing "Points" in the columns on the Players tab, because it is there by default, but just press the "Columns" button and add it if you aren't seeing it.
For the filters, there is a filter that you get by default named (appropriately enough) "Default". You can't change this filter. You need to create your own. Press the "New" button.
The upgrade should have "migrated" your preferences from the TD install folder to your "My Documents\The Tournament Director 2" folder (or "Documents\The Tournament Director 2" on Vista). You could try copying the "prefs.fs" file from the install folder (usually "C:\Program Files\The Tournament Director 2") to the "My Documents\The Tournament Director 2" folder. Make sure the TD is not running when you do this. And if you are using Vista, when you explore the install folder "C:\Program Files\The Tournament Director 2", you may need to press the "Compatibility Files" button to see the "prefs.fs" file.
