People having the 338 or the previous 358 driver version of Bluesoleil and considering to upgrade to this new 370 version, think again. 

After upgrading from 358 to 370 this week, I experienced:

- Disconnection of all Bleutooth devices after 5 minutes, due to a faulty reactivation of my legal s/n.
- After a while this is gone but replaced by: very distorted sound when using the A2DP service on (stereo) Bleutooth Senheisser headset.
- No proper swtiching between A2DP and HSP (Sco Audio) services and no A2DP sound on my Philips BT headset.
- I had to manually disconnect/reconnect the headset in the Bleusoleil Space window each time to get normal A2DP sound again.
- After reboot and automatic connection to my headset A2DP sound was distorted again.
- Windows error messages referring to BleusoleilCS.exe.
- Bluesoleil being inactive after a Windows reboot: grey systray icon. It could not be enabled by right-clicking this icon. Instead, I had to open the Bluesoleil Space windows, right-click the orange globe and select Turn on Bleutooth. After a Windows reboot the icon was grey and inactive again.

Deinstalling 370 and reinstalling 358 was no solution.  

I solved this in the end: deinstall the 370 version, manually delete all Bluesoleil entries in Windows 7 Registry (using regedit), remove my Bluetooth USB dongle, reboot Windows, reinstall the old 338 drivers which I downloaded by torrent, reboot Windows again, attach the USB dongle and pair my headset again. And lo' and behold: everything is working fine again! :)

So, please stay away from this 370 driver and wait for Bluesoleil to issue a new driver version. Bleusoleil should be aware of these problems, because more people in this comment section reported similar problems.
