Re:urgent help needed serious midi problems

The PumpDataMsec aud.ini value, which corresponds to the "prepare using N millisecond buffers", may need to be raised in order to avoid dropped MIDI notes or soft synths not playing at all. Using high-latency plugins such as PerfectSpace exacerbates the symptoms.
The default is 500ms, but if MIDI playback is unreliable CW recommends a setting of 700 or higher. Setting it too high will only cause latency problems if you're controlling outboard equipment via MIDI, but shouldn't be a concern if you're completely ITB.
I have never encountered this particular problem myself, and that's probably attributable to my practice of freezing soft synths individually prior to final mix/mastering. By the time I'm adding high-latency plugins to busses, MIDI buffering is no longer part of the equation because my projects have no active MIDI in them anymore.

All else is in doubt, so this is the truth I cling to.
