Unfortunately, I tried your tips and they didn't fix the problem. :'( I also noticed now that another program, MediaMonkey, is also having issues. I have an add-on called MagicNodes which runs a script to do its thingy... long story short, that add-on doesn't work anymore, and when I open MediaMonkey every time now it says something is preventing the script engine from running.
Any other ideas guys? I'm stuck in a rut, because uninstalling/reinstalling didn't seem to work either.
