Eyecon, catlin is right. It's the smaller button on the right that resume a render. The big one restarts it from scratch. As far as my rendertimes goes, my longest was 8 days (with the Old One). Now that I changed PC with a faster CPU (Athlon XP 2400), I can use ligthdomes and Premium Settings, that's so good, but my longest render was 70 hours ... So, CPU, squeeka. CPU is what really matters. S.
