I have a little problem.

I made this account today but when I log in my fawn turns into a frog, when the frog vanishes I'm left with the same antlers and mask they also vanish shortly after.
I also can't save my fawn as I get "failed to saved data" message.
I don't know what to do, I installed the newest version and tried running it as an administrator.

Has anyone some clues?
Thanks in advance!
