    I get error message "invalid plugin detected" and screen locks up.


      I have Window 7 and have attempted to upgrade to Adobe Reader 10 but I get this message.   I also get this message anytime I try to open a PDF file.  The file will open, but then this message comes on and it all locks up, so I have to delete.  This is a relative new Dell Inspiron computer.  However, I have no idea what an "invalid Plugin" is.   Any help would be appreciated.    Thanks,
