TeamSpeak Client not starting - error

Hi! I try to run TeamSpeak client on linux, Rasbian (modified Debian). When I execute the teamspeak3client_runscript.sh, I get the following error:

./ts3client_linux_x86: 1: ./ts3client_linux_x86: Syntax error: "(" unexpected

This is the only message I get, I am using version 3.0.17.
