I've been running WLM9 and Plus for quite a while. What I'm noticing is that it will bounce between working one day, and then not working for days after.  The button is still there but when you click it, it says software isn't loaded.  Sometimes it will come back when I restart, but it hasn't come back this time.  I'm not running any of the programs listed here.  Not sure why this is doing what it is but it's become a real PITA.  Help please?
