Glad you found a solution. Here is another possibility:

Perhaps your version of Emacs does not have the savehist library
preinstalled. If so, you might prefer savehist to .session - it saves only
histories, and you can control which histories to save. You can get a
version of it that works with Emacs versions as old as 20 here:
