They may well be migrating servers.Its just a case of playing the waiting game.Just use the retail discs for the time being.
Im having trouble with this as well the site works fine on my phone but cant access through laptop or pc also cant patch games.. There is no other program as far as im aware so just gonna have to sit back and wait for the issue to sort its self out.
No other software/site and gui will do ABGX's job.The site is now back up but running like a slug through salt.The site is hosted on the TX servers,which does not bode well as they always forget to put money in their electric meter.TX constantly has problems with its site.So if ABGX goes down inc the GUI then its a TX problem.
