IFR trainer software (and specifically OnTop 9.5), anyone?

[Ultranomad]

Colleagues, I am looking for IFR skill refresher software for a home simulator. I used ASA OnTop/ IPTrainer suite in the past and liked it a lot, but the old version I have isn't quite compatible with my current hardware, and the latest one (OnTop 9.5) has been discontinued and no one sells it anymore. Does anyone know where to get it, or could anyone recommend an adequate replacement? A full-fledged flight simulator like X-Plane might work, but I am specifically looking for the training functionality: specific exercises, automatic assessment of trainee's errors, flight data recorder, and the possibility to restart the flight from an arbitrary point along the track.

RANT? (Radio Aids Navigation Trainer)
From Oddsoft.
Still using it for FRTOL exams.
TOO

TheOddOne, thanks. Unfortunately, RANT provides the navaid procedures but does not support the yoke and does not seem to adequately simulate the actual cockpit workload (unexpected ATC instructions, turbulence, instrument failures, etc.), which is what I am actually looking for.
