It was working perfect until July 12 2009 it suddenly stopped working on hot mail.I changed to yahoo and it works again.Is ther a setting that needs to be changed for hot mail ? 

Yes, there are a couple of settings that you need to check if you’re unable to receive messages.  Sometimes, these settings contribute to non receiving of messages.  To give you an idea on what settings that might contribute to your issue, check out  the following Solution Articles below:
