error CS1061 help !!!

I have problem with script from UniRPG when i import asset to unity i have two errors in compiler :

1

Assets/UniRPG/Default Assets/GUI/Scripts/DefaultGameGUI.cs(191,35): error CS1061: Type `UnityEngine.AudioSource' does not contain a definition for `bypassReverbZones' and no extension method `bypassReverbZones' of type `UnityEngine.AudioSource' could be found (are you missing a using directive or an assembly reference?)

2

Assets/UniRPG/Default Assets/GUI/Scripts/DefaultGameGUI.cs(192,35): error CS1061: Type `UnityEngine.AudioSource' does not contain a definition for `bypassListenerEffects' and no extension method `bypassListenerEffects' of type `UnityEngine.AudioSource' could be found (are you missing a using directive or an assembly reference?)

So what is the problem with that script?. Help me! [21022-defaultgameguidata.txt (pls use notepad++ or something with numbers of lines)|21022]

The version of UniRPG you’re using doesn’t seem compatible with the version of Unity you’re using. You may be able to resolve the problem by commenting out the two offending lines of code. You may also wish to contact the provider of that Asset Store package directly for support, perhaps through their UniRPG support forum.
