ok, it does work on 7, i was being a bit thick.
what was happening, was that running a benchmark test to check my laptop can run it, it would close and the help center would pop up about something to do with not being able to open the help file for rebirth.
didn't read it properly til 5 mins ago.
turns out that as the help stuff for rebirth was written back in the days of Windows Help (winhlp32.exe) and that was taken out in vista onwards, it can't recognise the help files; in this case the getting started stuff, and as it couldn't open them, the program was closing.
go here to obtain the winhlp32.exe update for vista/7 to run rebirth on those systems.
