M/s outlook won't open. I get the following message. I installed a webcam but
problem didn't arise until 36 hours later despite several uses. Happened once
before after installing Norton package. Messages are as follows:
Business Contact Manager has encountered a problem and needs to close. We
are sorry for the inconvenience.
