Can you do one or more of the following:
1. Add the URL for the Lumion web site to the Trusted websites list in IE --> Internet Options --> Security Tab --> Trsuted Sites --> Sites and add http://forum.lumion3d.com/
2. You may need to check what Add-Ons are active in IE, and possibly Disable any you have doubts about.
3. Clear browsing History, in some cases for other sites where Cookies had run it means you may have to confirm the Cookie again: Internet Options --> General Tab --> Browsing History --> Delete button, and select Cookies and maybe the Temporary Files to clean out all old site visit files.
4. If none of above work to give good access over a few days, then Reset IE: Internet Options --> Advanced Tab --> Reset Internet Explorer Settings --> Settings button.
