When trying to access a link in a windows live mail message. I get a box containing the following message "C:\ProgramFile\WindowsLive\Installer\WLSRes.dll is either not designed to run in Windows or it contains an error. etc" I have not made any changes to the computer or installed new software since the last occasion it worked properly.  I am not sure if it is relevant but the electricity supply failed yesterday evening while the computer was on but not running any program. Help would be appreciated.
