Add another slash '/' before vehicle in the format line.

If you'd put that together with the complete directory address, it would look like this:

Win7: "C:\address_to_wherever_your_samp-server.exe_is_locatedvehicle\carsystemstring.ini"

But if you add / (which turns into \) it would be correct, like so: "C:\address_to_wherever_your_samp-server.exe_is_located\vehicle\carsystemstring.ini"
