PS4 Early Access Help

hi there I dunno if this is affecting other ppl but I will ask.

today I went to mogstation and upgraded my account from ps3 to ps4 which was successful it then gave me a code to use on the ps4 store to download the client which I did and then I used my early access code.

after that was done I went on the game but instead of taking me to the log in it took me to the terms n conditions page then it asked me if I had an existing account to which I entered my details.......

HOWEVER

on the next page it did not show my existing service account instead its showing me as a new user and it wont let me go any further unless I make a new service account (which I dnt want to happen)

ive tried reinstalling the client etc but it still keeps prompting me.

can anyone help me? did I do sumthing wrong?

any help would be most welcome :)
