Dell Netbook & Livestream viewing issues

I have a Dell netbook which I got through vodafone.Was away a few nights ago and thought I would tune in to Sexstation & Bangbabes.tv.However no picture viewable on either site.Have got Adobe flashplayer so am a bit puzzled.Have an older laptop which does do livestreams no problem so any ideas out there?Could it be a memory problem as the netbook doe not have huge on board memory.
