Krakatoa MX 2.1.4.48313, max2013, tp5sp1.1

I just updated the krakatoa beta build to the latest installment MX 2.1.4.48313. Same goes for thinking particles5, auto updated to latest sp1.1.0 via cebas product manager
I run max2013 with latest production update and subscription expansion pack. OS is win7-64

tp particles don’t show up period in krakatoa. is there a special procedure to follow after?

thanks in advance,
Anselm
