Unity 3D Obfuscator Pro version

Hello guy, i'm having a hard time trying to find the paid version of a well known app named "Unity 3D Obfuscator" for free. If some of you do not recognize this app, it's simply an app used to decompile/extract .unity3d files to access dlls and other things. Now the actual that i'm having is that i downloaded its free version/trial. This app has 2 main option that interests me. One is to decompile a .unity3d file and the other is to compile files that have been decompile once again into a whole and single .unity3d file. The first option is available in the trial but the second one is only available for the pro version and unfortunately it costs $149 on its main website.(I'm not allowed to post link, so just google it and check its price)

I hope that someone can help me on finding the pro version or in cracking it in some way. Thanks in advance for anyone who will help me.
