the instalation says that i need that to play online, my version is v 3.00, do i need it?

Yes and no. You do need to patch your game, but the one on the CD is way too old (if that's what you're talking about by WAPATCH). The current version of the game is 3.6.31.0
You can download the latest patch here:

I did that and then i tried to connect, but it told me i cant connect to the server and try other. But i was talking about the WaPatch, to patch the Worms Armageddon, not the Beta Update... i need some help :s

i have installed the Beta Update 3.6.31.0, then i tried to enter wormnet but it failed, it told me that i cant enter the server and try other... i downloaded Beta Update 3.6.31.0 and WaPatch (Program that i downloaded in wormsarmageddon.team17), but i dont know how to enter WORMNET, it fails every time i try, please help me... :(

Translates:
Error1: The instruction on "number" make reference to the memory on "number". The memory could not be "read".

Error2: Unknown software exception (number) in 0x00406947.

Error3: The instruction on "number" make reference to the memory on "number". The memory could not be "written".

Do i need WAPATCH in WA v. 3.00?

No.

The installer for the latest Beta update will download and install it if it's necessary. You do not need to install it manually.
