Spring RTS Engine

I have such problem. When try to enter in tasclient he offers me to download spring 91.0. I download this and open.
But for second time i want to enter he asking me to download spring 91.0 again and agin.
What can I do?

annoy the maintainer of tasclient to fix this bug or use an other lobby client: SpringLobby / Zero-K Lobby / NotaLobby.
