Aliases policy changed?

when I subscribed to Runbox it was stated that 100 aliases are allowed.
Now I deleted my 3rd alias and want to create a new one, but it says that it is an invalid request and through a link on alias page I’m directed to purchase an alias for 0,95 EUR… ?

There has been no change in the number of aliases an account can have (it’s still 100). I suggest you open a support ticket ( so we can look at your account settings for you. Thank you.
