Unity free crashing while running example scenes in Windows 8 (x64) and Android 4.0.3

Windows issue

When running the 01_LibPd_Basic scene - after stopping the scene the first time, and then after running a second consecutive time, Unity crashes (shuts down and then shows the error report window).

After the first run there is an error message at the bottom of Unity reading: 'Licence error. This plugin is only supported in Unity Pro!'.

The libpdcsharp.dll was copied to C:\Program Files (x86)\Unity\Editor.

System specs:

• MSI GE60 Intel i7-3630QM
• Unity Free 4.3.4f1
• Windows 8 (x64)
• NVidia GTX 660M GPU

Android issue

Similar behaviour is shown on my Android device.

The same scene crashes when run a second time on the device. This is after, for instance, when the home button is pressed to exit the app, and the app is launched again from the home screen.

Device specs:

• Huawei Ascend P1
• Unity Free 4.3.4f1
• Android 4.0.3

(note: regarding the Unity troubleshooting procedure for launch crashes:

• I'm assuming NativeActivity works on this iteration of Android, as was introduced with Gingerbread
• Disabling stripping is not relevant as is disabled by default in Unity free
• I'm also assuming that LibPd4 Unity would be classed as a native plugin
• I have not used ADB Logcat for troubleshooting as of yet
