System restore didn't work

Apparently husband informed me that system restore didn't work. Advanced System Care Pro 6 is still on the machine but I plan to uninstall it - haven't yet. The error message I get when trying to run windows live mail is a window with this message - all that is available to do is close program.
"A problem caused the program to stop working correctly. Windows will close the prograam and notify you if a solution is available."
