I just downgraded my account last week. The only thing to remember is that they only offer 1 downgrade per account, so you can't downgrade it again if you choose to upgrade it.
Yeah, exactly.
as per the mail paypal has sent to me after changing my premier account to personal, its clear that changing of the account type is possible (Downgrading) only once.
But if you are having upgrading issues, no problem- you can do it any time.
