Problem connecting

[Chapo]

Hello everyone!
Been a while since I last used MFBot, and I tried to use it again today.

The first time using it worked fine, but after a while it would refuse to connect to my account.
It keeps giving me a connection error, even tho the game and my internet are both fine.
It keeps giving me an error, more specifically "Error: input string was not in a correct format. That can occur if the network connection is not okay, or if the server isn't available or sth. like that."

Anyone had this before? It worked fine for a couple minutes...
