I just simply trying to make a file transfer. But after connecting I press button1, then file transfer OK. But if I pressed it again It gave me an error. Which is "The Operation is not allowed on non-connected...". So I made the button2 to connect again, but after pressing it it says i'm already connected. I read many articles regarding the error, but non of things worked for me. I even tried as admin but no work.
Please help me.
