I get logged out of Passwordstate instantly - why is this?

[support]

The most common causes for this type of error are:
 

• When using Internet Explorer, you may have the option of 'Never' checked for 'Check for newer versions of stored pages' under the Temporary Internet File screen
• We've found that McAfee Antivirus software can cause this - the On-Access scanning causes IIS sessions to be killed. Please try excluding the Passwordstate folder from An-Access scanning if possible
• The server doesn't belong to the Active Directory domain your account does - they need to be on the same domain
• If there is not enough free memory on your web server, the Application Pool in IIS can reset, which will cause sessions in Passwordstate to end
• The URL you're using to access Passwordstate has an underscore in it i.e. Passwordstate_7
• Problem occurs when trying to browse the Passwordstate web site on the Windows Server itself - this article may explain why - http://support.microsoft.com/kb/896861. Try browsing from a desktop computer to see if the problem persists.
