[HELP] BC gets stuck on IP reset

I've just started with BC and i've read all tutorials and topics about it.
I've configured my config.xml correctly, but i have 1 problem.
I start BC and choose Creation automatique, for making new pupils for my 2 main accounts.
My Reconnect.bat works perfectly on its own, but when it's run through BC, it stops halfway through changing IP so BC is stuck as well and i don't have an internet connection until i manually run Reconnect.bat again. Then, i have to close BC and open it again, but the same story happens.
I'm sure that my Reconnect.bat is correct, i configured it with 'curl'.
The problem shouldn't be in the config.xml either, it runs the bat file but for some reasons it doesn't finish the IP reset and BC just hangs there doing nothing.
Anyone can help me out with this issue?

Hmm, obviously there is an issue with reconnect files made with curl.
I've just edited the reconnect.bat file for Router Control and it works perfectly!
