Guild Wars 2

Greetings, my problem is this. when trying to purchase gems through the TP is imply get an error message reading (“Error” : “parse”, “type” : “ordermodel:error”) no additional info is given and i cant seem to figure it out.

I’m getting this error too a few days ago.

I was hoping the current updates fixed it but still the same error but only has

{
    "type" :"orderModel:error"
}

this time.

I’m on Mountain Lion 10.8.4. I’ve read on some of the posts here that to fix it, you have to login through a Windows client. But I don’t have a Windows computer.
