With these new updates two days ago, now I can't open a .docx document in Windows Live Mail.  With security on, it says "Prohibited File Type"; with security off, it says "The Microsoft product necessary to open this file is not installed on your computer." I use Microsoft WordStarter and never had a problem opening a .docx attachment in Windows Live Mail before.  What is going on?  Is there a fix other than having to buy a new Word program?
