Thanks for the files, Trev.
As expected, the update has been done incorrectly.
1) Try to update it next time as an administrator.
2) Don't install it into C:\Program Files or C:\Program Files (x86)

http://www.xmotorracing.com/forum/viewtopic.php?f=8&t=255&p=1338&hilit=3754117633#p1338your fce.ptn and fcr.ptn are wrong.
For example, your current fcr.ptn contains the string "3327465240" instead of "551634779".
The fce.ptn and fcr.ptn are unique for each update and version.
For the current update of version 1.43:
fce.ptn = "3754117633"
fcr.ptn = "551634779"
Try to fix them manually.
