After a few years, I decided to play this game again with other players' creatures. However, when I tried to log in, I encountered this issue (translate from rus: "There was an internal application error. Please try again.").
I wouldn't have asked for help if I hadn't tried some of different solutions: re-installed the game, re-installed EA app (yep, it's already EA version, not Steam or GOG), changed password (now it's 11 symbols length, includes only numbers and letters), looked for users with the same nickname (they don't exist (but why can't I find myself?...)), deleted the login.prop file, the whole folder in AppData and etc.
I searched for the same error on the Internet and found that I'm not alone with this problem, and so far no one has found a way to fix it.... So I decide to ask here - maybe someone knows what to do
Additional info: I have logged into the game before; I installed the game with EA app; I can still log in at https: //www.spore.com/ with used in game email and password; I have stable internet connection; I see how game trying to find and connect with account and then it give me a message of "This copy of the game will be linked to your account on spore.com" - after that, I see this error.
Maybe... After I changed the email address used in my EA account, I encountered this issue, but I don't think it's the actual cause
