WLM going through cancelling process – lost emails

Just came back to my laptop to find my WLM going through a cancelling process. Now I didn't start this and infact have never seen this happening before on my laptop but I think my cat Ruby might be involved as she has a tendency to sit on my keyboard which is nice and warm. Anyway I tried to click out of the cancelling process with no response then went to task manager and stopped WLM completely. I then went back into WLM and now find I have lost all my inbox email dating back to the 8/11/2015. What can I do to get them back? I've stopped keeping a copy on the mail server only recently so they are not there anymore. Would a system restore restore them? Any help/advice would be appreciated. Thanks.
