Outlook Express Shuts Down

CAS does what it is supposed to do, but immediately after OE finishes receiving mail I get the dreaded MS error window that OE needs to shut down and do you want to send an error report to MS. I have uninstalled CAS, and now OE is back to normal. Anyone got a suggestion?

Make sure you don’t have spyware\viruses, clean up your pc, make sure you have ALL updates needed. Do a chkdsk also and reinstall CAS and see how it goes.
