GET and POST to a webservice on ASP.net (c#)

but as you can see the first attempt fail and I need to reset the card, any clues on that?

I think that I explained that there... yes I have to press the reset button in the middle... may be my english was not good enough to express my thoughts lol

so basically and wrapping up the first time I run this, I got a connection fail, and then I push the reset button, and then it works perfect

only because you helped me
