Every time i try to click the battle.net button on the first screen of warcraft 3 frozen throne it says:
you may be trying to connect to an invalid battle.net server""
Whats this mean and what can i do to get on battle.net?

Your connection has been temporarily restricted from Battle.net. This restriction is realm-specific and can last up to 2 weeks.

It can happen for any of the following reasons:
- Using an invalid CD key
- Rapidly connecting and disconnecting to Battle.net
- Creating or joining numerous games within a short time period such as "Magic finding" or "Baal runs"
- By the use of "add-on programs"
- Chat channel abuse
- Failed login attempts
- In game latency caused by excessive spell effects

We are unable to lift these restrictions early or tell exactly why the restriction was placed on your connection.
