There appears to be several different ways to get arond the Save/Load options being greyed out.

An alternative has been suggested by ajtboy
This is what I posted a few hours ago...
1) When you see your Menu page that shows you can't save or load...simply click the "?" button on the top right.
2) Exit out of the campaign and game...sad to say whatever u did is lost!!!.
3) Re-launch the launcher...delete map.rwm...save...start the campaign.
This should kick start it...it worked for me.
