Hello, Katarzyna!
Thank you so much for sharing your question with us!
Since you're having issues linking your ticket to your account, I suggest
calling the Disneyland Resort and having the Cast Members assist you. Since wait times can be long, I recommend using a service like Skype to call using call credits, as calling from another country can be expensive.
There's another possibility: your original ticket could be expired (if it's an old one), and you may need to apply its value toward a new one. If your original ticket went unused,
you could be eligible to use its value in purchasing a new ticket. Don't forget to consider this possibility before you call!
I hope this answer helps you fix this tech glitch, Katarzyna. Please let us know if you have more questions about the
Disneyland Resort, and we'll be happy to help!
May the magic be with you,
Julie
