Runtime Error while testing motorTest.py

[Tros-t]

Hi, So first of all I wanna thank the creator for making my life easier. And second while I am running the test for the motors the code is same as from lib.mBot import * bot = mBot() #bot.startWithSerial("/dev/ttyUSB0") bot.startWithSerial('COM3') while(1): bot.doMove(100,100) sleep(2) bot.doMove(-100,-100) sleep(2) bot.doMove(0,0) sleep(2)

And the Error I get is:

`Traceback (most recent call last):

An attempt has been made to start a new process before the
current process has finished its bootstrapping phase.

    This probably means that you are not using fork to start your
    child processes and you have forgotten to use the proper idiom
    in the main module:

        if __name__ == '__main__':
            freeze_support()
            ...

    The "freeze_support()" line can be omitted if the program
    is not going to be frozen to produce an executable.

`

So kindly help me and I will create another issue for some more problems.
