I recently upgraded from Windows 7 to windows 10. Now I am unable to open Windows live mail. I tried going back to windows 7 and it will still not open. All my emails are saved in there and I have no other access to them. Is there any way to get around this and open windows live mail?

When I try to open windows live mail, it comes up as normal and says it is starting after a few moments another message pops up and says that it has stopped working and needs to close.

HELP
