PS4 Tsw 5 Dlc Installation Plus Profile Problems

Hello,

I am returning to TSW after a while and have problems after purchasing TSW5 in a special pack that appeared to include TSW 2020, 2,3,4 and 5.
I had TSW3 so that is ok but its a no show for 2020 ( not that worried) 2 ( similar)4 ( only the DLC really). 5 is installed but only has the DLC that comes with.

1. How do I get the DLC I have ( including TSW3) installed so that TSW5 can play them
2. I can restore my profile but this doesnt transfer the DLC. ( I have lost the email and password for this profile. I searched all my email accounts but chances are its been deleted )

Its a bit of a problem. Can anyone help?

 

Am I better off just lumping it and playing old DLC on TSW3 on PS4?
