Bloodborne Old Hunter Edition [duplicate]

I just recently got the Old Hunter Edition and everyone said that you'll be able to use the old save file from the regular base game. So I popped in the Old Hunter disc, hoping that my save file is still intact but I didn't see anything at all. So I tried out a tons of method from google but it still doesn't work! None of it. I didn't have the usual error that most people get, the error that says "Game incomplete".

I tried downloading my old save files to the Old Hunter Edition but it didn't worked either. I followed every single possible steps but none of it helped. I would greatly appreciated any help to solve this. I spent all my blood, sweat and tears to reach lvl100 with my trusty 10+ Tonitrus!!! Please help!!

I heard that you'll need to wait for about an hour or 2 to let it completely installed. I'm trying this right now and in the meantime, I'm redownloading my regular base game back since I thought the Old Hunter will work so I deleted it.
