LDN - Luminis Developer Network

Anyone using a file manager with Luminis IV? I've modified and configured ESUP File Manager Portlet to display files for download which works fine in uPortal 2.5. However, the moment I move the portlet to Luminis and modify the emptySessionPath to "true" for Tomcat's Connectors, luminis is unable to render any of it's channels in Internet Explorer. Any suggestions or advice would be greatly appreciated.
