Hey Matt, I just upgraded to the beta version--and that totally solved it! So, anyone else having issue with historical data...I second Matt's suggestion...solved everything & imported historical data is showing up now :)
Steps I took:
Settings > General Settings > select "The latest beta release" for version to use
Check for updates in the About Piwik box on the home dashboard
Use automatic update option. A white screen will appear. Click "back" in the browser.
Choose Continue to Piwik...
The screen for "Database update required" appears. It says to something via command line; I did so.
Ensure that "Delete old logs" is OFF in the Settings area
Delete the archive tables from the database
