What to do if on wolf quest lexicon chat is available

Assuming you meant the lexicon error "the online lexicon is unavailable", there are four possible reasons for this problem. Quoting from the WolfQuest FAQ article under "The Game- Multiplayer":
1) The lexicon file is unavailable because a new version is being uploaded onto the server.
2) The server is 'lagging' and the game can't load it.
3) Your internet connection is unreliable and the game can't load it.
4) There is some other temporary 'hiccup' with your internet or the game server; please try again later.
Keep in mind that if the multiplayer server is experiencing downtime or technical difficulties, you won't be able to play multiplayer at all until the issue has been resolved.

If in doubt, you're welcome to post on the WQ forums in the "Current Multiplayer Problems" thread found in the Tips, Hints, and Help forum though you will need to have registered an account before you can post there. I'll provide a link in the related links for easy access. The thread is usually stickied if there are any problems with multiplayer.
