When a Trial Key expires (or becomes invalid), it will stop access to the Wikitude SDK in a trial mode.
If you have any Studio Projects, you can continue accessing them in your Studio account. Your Commercial keys, Cloud and Studio API access (should you have them enabled) will not be affected.
In case your Trial Key has expired, and you need a new one, we’d be glad to review your request. Please go to your My Account page, find your expired Trial key, and press on the link ‘Request New Trial Key’ to submit your request for a new trial key.
