Awesome news to know! Thanks
Had the same problem with mine...
Turns out Scubapro (or Uwatec whom makes the scubapro computers) would seem to have tried to streamline supply in order to reduce costs....
End result, the AI receiver in the computer seems to be overly voltage sensitive -- remember that the rechargable button cells used in the rechargable computers, like the hud, are about .5v higher than the replaceable button cells used in our Luna 2.0's...
Turns out if the battery in the Luna 2.0ai computer gets below 3/4, the voltage goes too low for the receiver to work efficiently -- and it effectively becomes deaf... As the battery gets weaker (and voltage gets lower) the problem gets worse...
Put a FRESH new battery in the computer and it returns to working 100%!
Big note here... You may need to purchase your own battery outside the scubapro supply chain -- this type of battery does slowly self discharge over time and can already be discharged enough to not fix this problem by the time you receive it new... If the battery meter is not FULL once you put in the "new" battery, this is what happened...
Not sure if the receiver chip bias is accomplished via firmware, or descreate components, but presuming its firmware (as most are these days) it would really be nice if Scubapro would put out a firmware update to correct this...

That's more or less my point....
Mine came brand new with the battery already down to 3/4....
Worked perfect for about 10 dives, then started having problems receiving from the transmitter..... Just got worse and worse...
New battery in the computer corrected my problem...
Hope you get to go dive soon!
