Cannot Connect EA account.

I was connected for a period of time but I think the emails might have been messed up due to apple login on the phone using an iCloud while the EA account had a Gmail connected to the account on pc. Now i am only able to access the game on my mobile device and not on pc where i cant better run the game and see awesome graphics. Help please don't know how to fix as when I try to unlick the EA account on the mobile device it says its not possible. I have the codes to keep the account as it is mine.
