Checklist if the Code Doesn't Work
- It may have expired: Codes have a limited lifespan. If the developer has ended the validity period, the code is no longer valid.
- You may have entered the wrong ID: You need to enter your DevPlay ID in email format, not your player name.
- There may be a typo: A difference in upper/lower case or an extra space can invalidate the code. The safest way is to copy and paste the code.
- The code may have already been used: Each current code can only be used once per account. If you enter the same code a second time, the system will return an error.
