Well, your version comparison logic doesn't seem right, but I guess that depends on what you are wanting.

I would suggest starting as simple as possible with something like this:

sub EVENT_SAY {

	my $ClientVer = $client->GetClientVersion();
	quest::say("You are on Client Version: $ClientVer");

}

Then work your way up from there. Most likely something else in your script is breaking the script, which is causing the NPC not to respond.
