Hi,
I have problem with PDA ACER n50 and with bluetooth activation.
The problem appeared after ROM upgrading from v1.00.09 to v1.00.18
New ROM was downloaded from official ACER ftp.

Description of problem:
----------------------
When I turn ON bluetooth I got after some seconds message:
Sorry! Bluetooth can no longer be used because the license is expired.
BDA: 00:00:00:00:00:00
Key: E3E534E1...

PDA System info:
----------------
OS version: v4.21
ROM revision date: 20050818
ROM version: v1.00.18
Firmware version: v0.94
Bootloader version: v1.13

bluetooth info:
Bluetooth for Windows CE
BT-PPC Version 1.7.0 Build 1900

My unsuccessful efforts:
-----------------------
soft reset
hard reset
change of system datetime
older bluetooth versions application
- Widcomm 1.4.1.59
- Broadcom 1.6.0 0600
registry modifications
etc...

Can anybody help me with specific recommendation ?
