Hello, I have a problem with my C67ML Carta2. I submitted an issue through the form and I got an initial response from the the support team, but when I write them back, the mail is returned with the follwoing message:

(I’ve replaced the dots with underlines, or else it wouldn’t let me post because of the URLs)
