Hi All, please can someone help me wit some advice?

A recent power failure blew up my BeoPort which has been working fine for over 4 years (USB port stopped responding), so I managed to source another one (second-hand). On installing it the LinlPlayer2 software recognised the BeopPort but wouldn't connect to the Audio master (BS3200) or the video master (Avant). Despite trying various power cycling, rebooting Mac etc. the red symbols alongside audio & video master in preference panel stayed stubbornly red. The only thing of difference is the new BeoPort is firmware v1.30 & the older one was 1.31. 

To investigate further I connected the BeoPort to a PC running W7 & BeoPort app and the device then saw and happily controlled the remote audio & video masters. However, wheni tried the Advanced tab and firmware upgrade option the message came back " no need to upgrade"

My questions are:

1. Having search B&o's website I cannot find the 1.31 release of the firmware, where can I get this?

2. Does anyone with LinkPlayer2 have a BeoPort running 1.30 satisforily (if so I'm on the wrong track)?

3. Has anyone any ideas how I can get my "new" BeoPort to recognise my audio & video masters?

Thanks in advance,

Rob
