Tuneecu Not Reading Map But Shows Other Functions.

Can anyone work out what I'm doing wrong with tuneecu ?

Some history. I've not use the tune ecu programme for about 4 years. That was on my last bike. I never had a problem back then. I could remap at will, alter values and read off logged faults, etc, etc.

On my 2013 bonneville it's a different story. I'm using the same tuneecu programme with the same cable, ie no changes. I've downloaded a map I want to try in the bonneville. But when I connect it all up its as if the programme can't communicate with the ecu. The "connecting" light goes from static red through to flashing green then the display goes blank showing no colours . The laptop does show which map is currently loaded in the ecu, 20660, so it must be connected to some extent. I get a display saying unable to communicate with ecu and no values are displayed in any of the tables. It must be partially connected because I can access other parts of the programme.
I can open the test and adjustments screens or whatever they are called and am able to amend stuff if I want to.

It's got me baffled. Just to confirm, ignition is on. Kill switch set to run. Side and head light fuses pulled, (only had to pull one fuse on the tiger to kill the lights). Battery is fully charged and connected to charger as well.

Can anyone suggest what's going on please ? Pretty please !!
