Are you getting this when trying to connect to the server, or when you try to login a specific character? In some zones, such as Orgrimmar, there are random #132 errors because of high population. In this case, try logging a character that's saved in another city OR repair that specific character.
I get these errors all the time, especially in Orgrimmar. Fixing my character always helped. If it doesn't help you, repost here and a administrator will help you further with your issue.
By the way, did you download the full client? I suggest you download the original full version from battle.net, delete everything besides the Data folder, copy the Pandawow launcher over it and let it do it's thing. Then, download a config file suitable for your native language from here:http://forum.pandawow.ru/showthread.php?t=89935
