actually, the first link worked for me, so I don't understand vladimir.
About your problem, I'm a newb myself, so I don't know much about particles (only used them once very briefly), so I'm afraid I can't help :-/
I will however try it out next week if you still haven't solved the problem just to see if maybe I can figure it out (two heads think better than one anyway). I can't do it until next week because I'm very busy with a project (check my WIP thread) and I have an important test on monday. Sorry.
