Yeah the ruf is hard but you will get use to it.
I am pretty sure the real 787b used an h-shift which is crazy.
The carbon mod has these know issues.
V1.00 may have compatibility issues with Windows 8 OS. Do not install SweetFX or uninstall SweetFX.
If AC is not launching (crash on start) remove dxgi.dll and degi.fx and see if it solve the problem.
I would use JSGME mod enabler when installing the carbon mod which allows you to apply and remove individual mods from any game.
You can get it here:

Also HyperTek if you want to remove the carbon mod (and you didn't use the JSGME mod enabler) simply delete all folders with any part of it and run a steam integrity check; and you will be back to vanilla AC in minutes.
