Aidan i have just noticed forum questions from January 2012, yep almost 4 years ago regarding problems opening ports,same problem i asked about earlier.
As you know Aidan, Tim, the author of that request was asking why "grassgames" didn't fix the problem when it is an administrative problem.
Tim also asked you to invite him to have a look for you, but here we are, here jam, almost 5 years later and still the same problems exist.
When are you going to to do the right thing by your clients and give us a trouble free game.
