Hi Nick, CF8 is considered "End of Life" software by Adobe, they no longer support that version or provide patches for it (so it now has a growing list of unpatched security issues). You will want to run at least CF9, or CF10. There are two editions, Standard ($1499 USD retail) or Enterprise. Best way to buy CF is usually through a reseller, for the UK you can try: http://www.fuzzyorange.co.uk/ for the US you might try http://supportobjective.com/ because you can usually get a discount, but you can also buy it off the Adobe website. There was also a post on cf-talk recently by someone who has some CF9 licenses for sale: http://www.houseoffusion.com/groups/cf-talk/thread.cfm/threadid:64739
Thanks Peter, that's really helpful - I will post back once I know what we are doing in case my findings may be of use to anyone else.
Thanks again for replying - much appreciated.
Pete, just out of interest - who do you host with?
