I am running Windows 7 Home Edition (W7H), with Outlook 2007 from Microsoft Office 2007. I tried to open some .pst files created by Outlook XP on Windows XP. All I get a "cyclic redundancy check" error box. Is there a fix for this problem?

Please note that my .pst legacies are all in a "Trusted Folder" on W7H, so security-motivated file-open blockage in the Registry doesn't seem to be the issue here.
