Hi Paulo, thanks for the post. The event ID 269 shows that the issue can be caused by certain applications interfere with CardSpace: - Password Safe (v 3.07) - Acronis Scheduler Helper - Lotus Sametime 7.5 Let's check if they are on your computer and if CardSpace works again if you disable them. You can also check the following link regarding the event ID: http://www.eventid.net/display.asp?eventid=269&eventno=9999&source=CardSpace%203.0.0.0&phase=1 Hope this helps!Sean Zhu - MSFT
