Issues with Arturia's Analog Factory SE

[Amnesiac]

This plugins is crashes my PC entirely. Setup:

PT 7.3.1
Pentium IV 2.8GHz
Win XP SP2
RAM 1.5 Gb
Mbox2

Here are the circumstances:

1. Set AnalogFactory SE as plugin on an stereo track (it wont appear as an option on a mono track)
2. Start edting notes. It works well for a while
3. Suddenly, while several notes are playing at the same time, the sound freezes in a short cicle (about half a second). It freezes the session. The computer. crashes completely. Cant open the task manager. This makes it necessary to have to press the reset button.

Any ideas on why this might be? What can I do to fix it? I reinstalled the plugin and it doesnt work.

It would be a shame to not be able to use this plugin.

Thanks in advance
