Enter a code (at least 4 characters)
Redeem form shows account.redeem.codeTooShort when the code is empty or under 4 characters.
Why this happens
Client validation before redeem — not “invalid code” from the server after a full attempt.
Diagnose and fix
1. Paste the full premium/reseller code (at least 4 characters).
2. Remove extra spaces; retry.
3. See Redeem a premium key.
4. If the code is long enough but rejected, use the invalid-code Help for that product string.
