Cant connect via Bluetooth using Design 7.0?

We have a G12 installed in a system, and I seem unable to connect using IQANDesign 7. IQAN Run 7 works fine and I can see values etc but if I monitor in IQAN Design it refuses to connect. The flash sequence on G12 is 'connected' but I cant seem to get it to work, it eventually errors.

I may be missing something, does anyone have any advice? IQAN Go on the mobile appears to work fine, no issues.
