Windows 7: Replace default .pst file with existing .pst file

I upgraded from Vista Business to Seven Home Premium. Used Office 2007 in Vista and using it in Seven. In Vista, my .pst file was C:\Outlook\MyOutlookFolder.pst. Added it to Outlook using Data File Management, but none of my calendar entries appeared (my inbox and all my other folders are OK). When I upgraded from XP to Vista, this worked fine.

Where are my Calendar entries?

if you had any backup for that then just insert that in outlook or open it in software...
how did you upgrade your OS, its better to back up your information and install an new fresh installation

Thank you for your replies. I already did both of those. Since I keep my .pst file outside of C:\Users\..., the upgrade didn't touch it. But when I link Outlook to my .pst file, I get all my folders back OK, but all my Calendar items are missing.
