we used lightstreamer 4.0 and now upgrading to 5.1, we now use the demo license for testing.
I first rebuilt the adapter, .net client using new .net SDKs.
when the .net client try to connect to lightstreamer server, we got the exception on the client side:
connection error: Lightstreamer.DotNet.Client.PushServerException: Incorrect answer: <!--
at Lightstreamer.DotNet.Client.ExtConnectionListener.WaitStreamingTimeoutAnswer()
at Lightstreamer.DotNet.Client.LSClient.OpenConnection(ConnectionInfo info, IConnectionListener listener)
at LightstreamClient.ConnectHelper(Int32 ph)
while on the lightstreamer server log, we got

I hided the LS_user and LS_adapter parameters.
by reading documentations, it looks like the lightstreamer server configuration does not support the Text mode protocol. if this is the case, how do I configure it to support Text mode? if not, what is the problem here?
