I have my laptop with 2GB ram and since I started using AE CS3 I always get this "insufficient RAM" error, and I can't even render my full video for RAM preview (when it renders new frames it deletes the old ones, and I can only render about 7 seconds from my 12 second video).. I went to my preferences, I added 2 more gigs of HDD for After Effects to use, but I still get that error.. The thing is that my clip isnt something special, few mask and few layers and in the older AE versions evrything would flow with out a problem.. Does CS3 eats that much of RAM or I dont know something???
