For the last two days, when I try to create a subfolder in Outlook Express, the response is a message box saying "The folder could not be created. An error has occurred."

When I try to use the Outlook Express 5 link from Microsoft's support page, I get a message "Outlook Express could not be started. It may not be installed correctly. Make sure that your disk is not full or that you are not out of memory. Contact Microsoft support for further assistance. (0x800C013E)"

I redownloaded and reinstalled IE 5.5. This did not solve either problem.

Can anyone suggest ways to fix this?

I'm running IE 5.5 with Outlook Express 5.5 on a Windows 98 PII 400 system.
