Help required regarding custom client.

Good day,

I'm having an issue with custom client, the Open tibia server I'm playing is only avaliable to play thru custom client which you download from their site. Is there any possibility that I activate WindBot with custom client which is 11.44.5516.It's a good OT and I'm gonna play it for a long time, I would very appreciate if someone helps.

Thing is it does recognize the client with (?) and when I click load it just goes Not responding.

Thanks in advance.
