I have a browser extension that lets me send a link to my current browser page using my email client. My email client is WLM. When I try to use the extension I receive Microsoft's error message telling me that WLDcore.dll is missing from my computer, and I should reinstall WLM. I accordingly uninstalled and reinstalled Windows Live Essentials (for WLM), and there's no change. Please note that there does not seem to be any other problem with WLM--I can send and receive messages as usual. Can you explain what's going on?
