Thanks - def will.
Is the logitech profiler now called Logitech Gaming Software? I can't seem to find the download for just the logitech profiler. I feel like I tried the gaming software and it installed fine but when I loaded it, it said no devices found so maybe I d/l the wrong thing (should have got profiler)?
I came across this problem last night. The latest versions don't support the G27 (and presumably the G25 and DFP/GT) so you have to download 5.10.
There are different versions for 32 and 64 bit OS.
32-bit install: http://www.logitech.com/pub/techsupport/joystick/lgs510.exe
64-bit install: http://www.logitech.com/pub/techsupport/joystick/lgs510_x64.exe
