I had that problem even after I installed a total of 4 GB RAM. The trick in my case was to set the /3G switch at the end of the last line in the boot.ini file. This is recommended by Adobe in their Read Me file on the installation disk to make usage of RAM above 2GB. In my case this solved the problem. Without that switch PP2 crashed even when 1.6 GB RAM were still available. – I hope this helps.
