Welcome to Adobe Forum,
You have purchased Single App CC for Photoshop on March 11th 2014, paying monthly.
You can upgrade to full CC by paying monthly or at one time yearly fee.
thanks for your answer.
And thanks for the links, but I found these by my self and they didn't helped me out.
Because I don't have a button "Learn more" or something like that under my plans to handle the things thats in your FAQ.
Sorry, this is in german, but I think its enough to show you, theres no option like the FAQ-Screenshots.
And when I try to buy a the full membership, the system/website tells me I can't, cause I already own one
of the software in the package (in my case Photoshop).
Maybe I'm blind or its simply not possible for me.
Thanks for your response, I got your issue, it would be best to upgrade via Adobe Contact.
They will be canceling the present CC & providing the new one too.
