texmacs plugin for Maxima?



I'm trying to use Texmacs 1.0.7.17, (I haven't used it in a long time)
  and find it doesn't seem to work with Maxima.

If I choose Insert-> Session-> Maxima  I see a red [busy...]
and then Maxima]
  in the window,
but it does not seem to react,  although there is now a menu item for
Maxima with selections for Simplification,Solving Equations, ...

I am using Windows XP, Maxima version 5.30.0, GCL 2.6.8.

In the Texmacs plug-in folder, if I execute maxima_detect  I get #f.

Perhaps it is looking for
  c:\maxima-5.30.0\doc\info\maxima_toc.html
or
  c:\Program Files ...maxima_toc.html

which is no longer there.


or is there something else I should try?
