pixel_player52904889 Just a small hint: you can play Seaport via Google Play Store, Apple App Store, Amazon App Store, Facebook or as a browser game from the portal page on a variety of different browsers on different PCs (Windows, Mac, Linux...).
Without telling what you are trying to do and on which platform and at which point you got stuck, probably with an error message you should also mention, noone can even understand what's wrong for you and because of this noone can help.
Because of the lots of platforms and things you can try, it is very impossible you will even meet one player here who got the same error because he has the very same situation as you. 😉
I could tell you I recently updated Seaport without any problem, but without telling you which platform I used, this information is completely useless for you and wouldn't help you.
So if you want others to help you, you need to go into the details.
