I've checked xc files in xvm config folder and I've found problems in several files such as vehiclename, carousel, clocks, etc....
There should be "/" character at the first line that represents remark phrase starts from there,
but i found some strange character in place of "/"
And when i start battles, I read error message that says error found in those files.
It seems installer changed "/" and following characters into some other character.
maybe local problem, but i hope you check with this.
