Help with Fordson Convert Please

[Craig Dancks]

Hi, I am trying to convert NI Modding's fordson conversions pack (counties, doe, plowmaster and crawler) from fs13 to fs17 for private use. I am able to get the mods into the game and can purchase them, however, when I attempt to drive them, they won't move, and most of the controls freeze up. The error that I am getting is "Error: Running LUA method 'update'.
dataS/scripts/utils/Utils.lua(298) : attempt to perform arithmetic on local 'v2' (a nil value)"
I can see from this that the problem lies with the custom scripts the mod has, but I don't know what to do about it (I have included my log file) .I have tried taking the script files out of the folder but that doesn't work. Would anyone be able to tell me how to fix this error? I don't really mind if it involves getting rid of the scripts entirely, as I just want the tractors to work ingame.
Thanks
