I use Windows Live Mail 2012. I have had no issues with this program for the many years that I have used it until just a few days ago. I am looking at ads in Craigslist, I click on reply, I then click on the email address and get the following System Error in a small box:

wlmail.exe - System Error

Big Red X then the following statement: The program can't start because WLDCore.dll is missing from your computer. Try reinstalling the program to fix this problem.

I did uninstall and reinstall WLM but it did not help any. Now I have to copy the email address, open an email and paste the email address into the email.

What can be done to fix this problem? Thank you in advance for your assistance.
