After running the updater to the current version of There, some members may receive the error "Could not advice from hardware checker".
This error indicates that somehow, an old There install and a new There install have been mixed up, and the registry is not correct for the way the new There client launches.
The swiftest method to repair this is to uninstall There from add/remove programs, and then download and reinstall using the full version installer from:
http://www.there.com/downloads
This will resolve the issue and allow login without this error.
