"Wrong password" on PS3, but works on PC?

Hey, im a legacy 1.0 player who bought a ps3 version of the game to play on both platforms.

I redeemed the code on PSN and i was able to start the game. But when i was gonna link my SE account on the ps3 i could not login. It keeps saying wrong password even tho its working perfectly fine on PC both before and after trying on the ps3.

Anyone else have this problem?

I'm having difficulty to get SEN and SQEX service account linked. I got the "No valid service account" error... My FFXIV is Standard digital copy from PSN.
