I was issued a Licensekey.

```auto
Exxxx-xxxxx-xxxxx-xxxxx-xxxxx-xxxxx-xxxxxxxxxxxu

```

It’s being implemented like the page below.

However, WowzaGOcoder does not seem to be initializing.

```auto
goCoder = WowzaGoCoder.init(applicationContext, mLicenseKey)

```

Tell me Why!!!

java.lang.IllegalStateException: goCoderInitError must not be null

Because that’s not an GoCoder SDK license key. We stopped issuing those on April 2, 2020. That’s an Engine License key that begins with “E” and will not work when you enter it as the GoCoder key that would’ve started with “G”.
