Hello;
Today I installed the upgrade on my laptop day in 20/12/2012 which had not yet installed the upgrade 12/12/2012 and attempting to start the program I get a note saying;

Unable to open 'marks'. please contact Project Pluto

If peak in accepting the program starts normally and the warning disappears.
