Can not connect to Nokia PC Suite

After a successful installation, it is neither me nor managed by the PC from the laptop using the Nokia PC Suite on the Nokia E60 to access. In addition, in my view, be too many options installed, which can cause immense phone bills in incorrect operation (telephone modem, Internet gateway). The operating conditions of the supplied, extensive software packages can not simply check and clear off. So I activated an audio connection (headset to E60) and but found no way to disconnect it. The phone always the symbol remained activated.

An alternative Bluetooth Dongle working properly on the same equipment.
