I can't play worms world party because it said to insert worms world party. How to fix this problem? Sometimes it said to close the program, how to fix this problem?

Either insert the CD or if you've inserted the CD, ensure you've installed the correct patch for your CD's release region. http://wormsworldparty.team17.com/main.html?page=comm&area=_down_patc shows pictures of the 3 different WWP CDs and has links to their associated patches. Make sure you've downloaded and installed the right one.

Since my thread aint showing up i guess i can write in under the topic "Worms World Party Problems".

Whenever i host a game and my friends tries to join it the ip he is connecting to is my local - "192.168.0.x" and not my public one.
I've tried to force it to pick my public one by entering it in the configuration before im entering WormNet..

Anyone knows how to solve this?
