This happened to me too, but it was just a one time problem for me as for now (plus I COULD join the fishing squares, not the regular squares). I went to do something else and checked back on lunia 3 days later and the regular squares did work fine for me then, happened just one time and hope it stay this way.
So when this happens to you, try one of the fishing square's (first half square's are Regular second half is Fishing, dont ask me the difference between the two of em), or wait some time and try again.
It's all I got for "solution" about this, hope someone else knows more about this problem.
