Hi,
I have to say I think that's extremely unlikely at this point.
Currently PGO has 59 (!) active original users and 2 new users who started with PGO v4.
I would estimate that I am out of pocket for the development of PGO v4 by a few thousand dollars (minus the $49 for the two new licences

)
It would not make financial sense to spend more money on development time producing a cut down, free, version of PGO. Unless some miracle occurred and I suddenly sold a couple of hundred licences to new users.
Trust me, no one is more sorry about this state of affairs than I am.
Cheers,
Wilson.
