Switching account information

[Bluetopia86]

I myself, currently have a premium account with Spotify. My fiance' and I live together and he just signed up for school and is officially a student. I was trying to update my profile for the student discount, i put his name in, and his credit card information, but I'm getting a CSRF token invalidation error message. Do i need to change all the info in my account settings to his email and name ? And will i lose all my music in the process? Please help!! I've spent so long creating my albums and playlists. What should i do ?
