For Dragon Age: Inquisition on the PlayStation 4, a GameFAQs Q&A question titled "What effects does the "Witch Hunt" DLC have?".
Good to hear that you can finally play the game. However, your advice seems to be only valid for PC users. I live in India too and I managed to buy the game for my PS4 by creating a US account, buying a 50$ PSN gift card from Amazon and downloading it from that US account.
IF you had backed up your data in the recent past, you MAY have access to them in the backups you made. C:\Users\ Your user name \BioWare\Dragon Age Inquisition\Save. ^^ typical location for saves from DAI and in general all Bioware games.
I had never even played DA:I on pc before so when i launched the game for the very first time it told me that i dont have access, it also doesnt even show up in my library, whereas Dragon Age 2 (bought at the same time and just finished playing) worked instantly without any issue aside from some dlc stuff i sorted out later.CGKi.
