Outlook 2003 - Any .PST File Operation Crashes Outlook (windows 7-64)?

whatever i try to do on my outlook that has to do with .PST file management results in a crash where outlook quitsif i go to control panel > mail settings > data files 2 of the files that are in use (& work) do not show up, one of them the default mail delivery .PST. in these two, trying to access the advanced properties gives an error:The operation failed. An object could not be found.now - general googling tells me that recreating the profile could perhaps fix this - but i would love to avoid that as there's no manageable UI to set up the email accounts and there's many in use.event log on trying to open a pre-existing .PST that's not in the current profile:
