Do you have an old account? If yes, try entering via GoogleSearch the old web side an log in. mybe you'll find it there under downloads. Once I tried it this way cause i couldnt log in on the new page at the beginning. i read that also other customers with older accounts have trouble loggin in on the new page.
ok i have tried that and it says invalid download ID so i cant even download the update off the old site now aswell, its really pissing me off since i need to upgrade to use the new consoles i just bought
