I get an error that I can't fix, It's when I try to add the web reference. Could you help me?

Parse error: syntax error, unexpected $end in /home/mcserver/public_html/server/lib/nusoap.php on line 5743

I think you have to re download library and re-upload to your server.your file might be corrupt.
