I am in need of help please! I know that sounds really desparate but I am at my wits end with this problem. I am using Heusenveld Ultimate pedals in my rig and it seems maybe that R3E maybe doesnt like them? What happens is when I have the HE's plugged in and start the game my mouse cursor goes straight to the bottom of the window and when I try to move it, it just wants to stay right at the bottom for some reason. I am using a Asus G751 Gaming Laptop for my PC. Every other racing sim works just fine with the HE pedals plugged in. all but R3E. When I unplug the HE pedals all is fine in R3E and I can use the mouse pad or separate mouse just fine. I need this to work to set up my wheel and pedals,etc. but this makes it impossible to navigate at all. Man, this is driving me crazy. I have done everything possible including reformat my PC. I really want my R3E back!!! I even replaced the controller box on my HE pedals also to no avail.
Late to the party but have you calibrated your pedals per HE's instructions with DLView ? https://www.h-engineering.net/support/sim-pedals-ultimate/
