Purchased Lightroom 3 then got a complimentary upgrade to version 4, last week i got a new computer.
my account at adobe.com only has me listed at version 3
i tried loading version 4 with my v3 serial number and that did not work.
adobe chat says the can not help, and suggested i ask here.
all my files are in version 4 and will not open in version 3
It is not Possible to open a Previous version catalog in Lightroom

You must have got a Lightroom 4 Serial number with the upgrade?(do not share it here)
If so try using it.Refer Find your Adobe product serial number quickly to find your Serial number.
