ah, ok
when I first installed the program, I had used the
Tools / Install Additional Files
option from the menu and copied the projects and files to my D drive
so I guess Steam did an update, but the files were in the Steam folder and not in my D drive
So I re-ran the Install Additional Files and it got updated
I can now see the new 2013 project, but now when I compile I get
error LNK1104: cannot open file 'atls.lib'
is this because I have the Express version ?
Microsoft Visual Studio Express 2013 for Windows Desktop
edit:
ok, found the "solution"
apparently the Express edition is the problem
according to this

atls.lib is NOT included in the Express version
apparently you have to download
Windows Driver Kit v7.1.0
and then build your own libraries ?
eh, too much trouble
