Upgrade plan expired

[NK94]

Hi all,

The other day, it appeared that I'm running a version of Pro Tools that is too old for my operating system (high sierra).
I went into avid.com to download PT 12.8.2, but then I discovered that my annual upgrade plan was expired because my payment information was out-of-date.
I updated the information but I still can't find a newer version than 12.7.1 among my download links under "My products and subscriptions".
Maybe I need to manually renew the plan?
I checked on options for that and then I saw that a plan now will cost around €270/year.
Since I only paid €89/year before, I wonder if this is correct or if I'm doing something wrong here.

Thanks in advance for your help!

Best,
Niklas
