SharePoint 2010 Web Analytics Unexpected Error

When I access the web analytics report at http://domain.com/_layouts/WebAnalytics/Report.aspx?t=SummaryReport&l=sc I get the error below:

An unexpected error has occurred.

Troubleshoot issues with Microsoft SharePoint Foundation.

Correlation ID: [guid]

Date and Time: 1/17/2011 12:36:12 PM

Checked the SharePoint logs for the Correlation ID and got the three errors below:

Also, we have multiple site collections on that web application, some were migrated from 2007 (we'll call one /sites/2007) and some were pure 2010 (we'll call one /sites/2010/). The error is only showing for the pure 2010 sites cols, while the migrated sites cols are working fine. I'm still looking for other differences between the site cols.

Also, if I go into Central Admin > View web analytics reports > choose that web application, and go to Top Pages i can see stats for both /sites/2007/ and /sites/2010/ so the analytics are being captured for all site collections, I just can't access the reports on the /sites/2010/ site collection due to the error above.

Any help would be greatly appreciated.
