Trouble with Detonator

Hiya.

I'm banging my head against the wall right now. Been at this for several hours.

You see, I have the Detonator package imported. Many of you probably know about it. It's quite awesome.

Except that I can't get it to work.

I imported Detonator into my project, but there were transparency issues with the smoke. I searched the web, and found out it can be easily fixed just by pressing "Ignore" when Unity wants to turn some textures into normal maps, the smoke texture between them. It states that some Material uses them as normal maps and they have to be set as normal maps.

I tried to Instantiate the Detonator-Base prefab.

And hooray. It worked. In the editor. In the build, whether it's Linux or Windows, 32 bit or 64 bit, it gives a

 NullReferenceException

   at Detonator.Awake () [0x00000] in C:\users\krabica\Moje dokumenty\Tunnelers-Unified\Assets\Detonator\System\Detonator.cs:171

When I build the project with just the test map, it works perfectly.

Please help. Please.

Thanks.
