From Support Centre's FAQ: Can friends and family play simultaneously if they are on different accounts?

Can friends and family play simultaneously if they are on different accounts?

This is possible, although the requirements differ depending which platform you use.

Windows only: e.g. to use 3 accounts simultaneously, you need:
- 3 Square Enix accounts
- 3 copies of the Windows version
- 3 PCs

Windows + PlayStation 3: To use an account from each version simultaneously, you need:
- 2 Square Enix accounts
- A copy of the Windows version
- A copy of the PlayStation 3 version
- A PC
- A PlayStation 3 console

PlayStation 3 only: To use 3 characters simultaneously, you need:
- 3 Square Enix accounts
- 3 Sony Entertainment Network accounts
- 3 copies of the PlayStation 3 version of the game
- 3 PlayStation 3 consoles

well this is wrong, for windows i can have one squareenix account and 3 service account tied to it. for window+ ps3 you can have as much window service account tied to it, but only one psn account. Even if you are to upgrade your windows version to add a ps3 account you cant, it your already have one psn account tied to your squareenix account.
the problem is i have a ps3 account and a windows version tied to one square id, and i want to upgrade my windows version to be able to play on ps3 but i can't.
