Window Mail Will Not Load

The first error message I get is
"Windows Mail could not be started. The application was unable to open the Windows Mail message store. Your Windows Mail mailbox data is currently being used by another program, such as a virus scanner. Close the program or wait for it to complete its operation, then open Windows Mail again. (0x800C0155, 2)"

I am running McAfee Anti Virus program and the next error message I get is
"Windows Mail could not be started because MSOE.DLL could not be initialized.

My MSN Messenger will not open as well and I have to access my email theough my ISP.
