couldn't load script - invalid xml format (expected=)!

Hello

I set up my config and save it. I couldnt load it and the error is "invalid xml format (expected=)!" I have checked my documents and I have document .xbst but I dont have document .lua in scripts folder. I tried to make one with notepad, I save the file as .lua restart the client and xenobot and still coulnt load this script. When I download scripts from "settings-> get scripts" everythings working. I just can't load my own scripts. Does somebody know how to fix it?
