I have Compaq P4 running Win XP PRO. I have installed IrDA Device BF-120 (www.bafo.com) which automatically detects the USB to IrDA diriver and installs it. In order to connect to GPRS when I try to install and update the Nokia 6610 (IrDA) driver it lists the compatible hardwares and when I select Nokia 6610 (IrDA) bleow it shows "This driver is not digitally signed!" then I press Next to install the driver it starts copying the files and window opens with the message "The software you are installing for this hardware: Nokia 6610 (IrDA) has not passed Windows Logo testing to verify its compatibility with Windows XP. Continuing your installation of this software may impair or destabilize the correct operation of your system either immediately or in the future. Micrisoft strongly recomments that you stop this installation now and contact the hardware vendor that has passed Windows Logo testing." Then it displays "Continue Anyway or STOP Installation". After clicking "Continue anyway" icon it installs the driver. After that when I dial GPRS connection using my Nokia 6610 and IrDA device it starts dialing and in a few seconds displays "Wireless Link Interrupted! Your link is either blocked or the device has moved out of range" and it disconnects after that.

Can anyone help me how to sort out this problem? I have tried with installing it in WIN 98 and works fine in laptop.
