Raildriver Calibration Issues

I recently purchased a Raildriver Controller for use in train sim games, mainly OpenBVE. Although, in the Customize Controls section, all the axes show as fully lowered, and none of the buttons show up on the menu when pressed. I presumed this was because I hadn't calibrated it through the Options menu yet, but on the Calibration menu (after clicking launch), the Next button does absolutely nothing, so I am unable to calibrate it. This isn't due to defective hardware on the controller, since it works perfectly on Train Simulator (aka Railworks). I tried searching the web and these forums for answers, but the only one I found (https://sites.google.com/site/raildriver4openbve) didn't work. Anyone have a solution? Thanks.

EDIT: I just installed the most recent version of OpenBVE, and the axes and buttons now show up correctly on the Control Customization screen, but the Calibration still doesn't work.

Apologies, moving to 64-bit accidentially broke the calibration dialog. (as there are now two copies of the RailDriver 'driver')

I've fixed this for today's daily build.
Should hopefully get a later release pushed in a week or so.

Just downloaded it, works perfectly. Thanks!
