Due to an error of the internal memory management there is a new update of Py4D available which you can get via the Py4D Onlineupdater or as a complete package (see ‘Get Py4D’). In a few cases the NetRENDER of CINEMA 4D does not startup properly(v0.9.6500 and v0.9.7101). This update is recommended to all users. Py4D 0.9.7150 works stable and fine on all systems.
