[Help] I got PS3 License but wanted to upgrade to PS4 License

[blood618]

Hi All,

Sorry for the trouble. I need help about this and i've read a lot of articles about this and I still haven't found a solution.

I recently purchased a PS3 License for it to be upgraded to PS4 license.. the problem is that I do not have a PS3 console but have a PS4 console.

I don't know in playstation network if PS4 and PS3 are same but when I tried to put in my PS3 Code on the PS4 Redeem codes it didn't work.

Now im trying to find a way on how to login to PS3 Network to register my game online w/o a PS3.

Error : "The Prepaid Card code you entered is incorrect or is no longer valid"
currently in : Singapore
Licensed used : UK

and If ever there is no choice I may have to buy a PS3 next month. my only concern is that if the Licenses code didn't work by that time i wont be able to request for a refund on my license.

Thanks for those who will read or reply.

regards!
