Hi newbie here *waves*

spent the last 2 hours trying to find a fix,
have unistalled 6.1 737
, tried to re-insatll 5.5 and couldnt (or rather it wouldnt), have managed to get 6.0 667 back on but has same problem.
Starts at around 40MB and soon zooms up to 200mb+ and gets to around 700mb after 30 minutes or so - its causing real problems when trying to load Cubase/Cakewalk etc
Its the 'free' version'
and I have a firewall on my Linksys router
XP Pro SP21gb RAM
(oh for the record.....Im a senior solutions architect
in CA and SMS/MOM...so be as in depth as you like)
many thanks
