Also it says

The connected PSP system is activated with a different account, if you perform this operation the current activation will become invalid

Do you want to continue?

Okay here is the story, I have had two accounts, my first one is where I have bought Spyro 3 and Silent Hill.

My new and NOW main account is where I have bought MGS1.

Okay I want to put all three of them on my PSP for when I go on vacation tomorrow.

I have had my PSP when I created my first account and I have put PSone classics on there before, and those games work, but when I try and put MGS1 on there from my new account it says this will become invalid.

And yes MGS1 became invalid today after I put Silent Hill on it.

Oh and I do not have an online account on my PSP, I never have.

Sorry I messed up, my new account is my new main account.
