After two months trying to get a proper install of my Sitecom Bluetooth Dongle CN-500, I still have the following problems:

1. When I double click on the bluetooth icon in my system tray, I get a message which I cannot solve, the message is:

Bt wizard, incorrect license type

2. Open 'Control panel' -> 'Bluetooth configuration' -> 'Accessibility' . Check 'Let other bluetooth devices discover this computer' option and set 'Devices allowed to connect to this computer' to 'All devices.' Get an Error message on apply:

Error in Bleutooth services: There is an error when saving the changes, the following changes are not saved:
- Discovery
- Connections

What did I do so far to get it right:, beside uninstall-install everything more than one time.
- I made a back-up of my register and deleted all register keys with the word Bluetooth, in total of 310 keys. But this solved not the problem, it became only a bigger problem because my PC didnot start anymore. Lucky I know more, so started in safe mode, put the back-up back in place and the PC started again, pffft.

- Changed the files bth.inf and bth.pnf to *.old in de inf folder of windows

- Deleted register key: HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Control\Class\{e0cbf06c-cd8b-4647-bb8a-263b43f0f974}

- Follow several manuels and tried them out:

3.1 CN-500v2 USB Bluetooth adapter Driver v3.0.1.910
3.2 CN-500v1/501/502/504 Bluetooth adapter Driver version 1.4.2.11
3.3 CN-500/CN-502 USB Bluetooth adapter License burn utility

At this moment I have two bleu/white bluetooth icons in my systemtray. When I try to pair my Nokia 6600 to the PC, one of them turns bleu/green for several seconds, but cannot be connected.

As you will understand (may be) I am getting a bit desperate. What more do I need to do???
