Nah, this is an old bug and is easily fixed - the latest version of GPxSAT doesn't recognise changes in upper/lower case so well. Go into your GPxPdata folder and you'll see a file there called gpxsat.ini
Firstly make a back up.
Open the file in Notepad, then in [STRING] section change all the strings to upper case. ie:
[String]
Section=String
Intermediate1=INTERMEDIATE 1
Intermediate2=INTERMEDIATE 2
FinishLine=FINISH LINE
PitStop=PIT STOP
WarmupLap=WARM-UP LAP
OutOfTheRace=OUT OF THE RACE
IsOutOfTheRace=IS OUT OF THE RACE
Accident=ACCIDENT
InThePits=IN THE PITS
IsInThePits=IS IN THE PITS
RaceWinner=RACE WINNER
FastestLap=FASTEST LAP
Lap=LAP
Laps=LAPS
LapsCompleted=LAPS COMPLETED
LapsRemaining=LAPS REMAINING
FinalLap=FINAL LAP
Out=OUT
SessionOver=SESSION OVER
RaceOver=RACE OVER
Leader=LEADER
PolePosition=POLE POSITION
Classification=CLASSIFICATION
Speed=SPEED
Current=CURRENT
TopSpeeds=TOP SPEEDS
CurrentSpeed=CURRENT SPEED
DriveThrough=DRIVE THROUGH
ClassicPenalty=P E N A L T Y
DigitalPenalty=PENALTY
Winner=WINNER
Hope this helps you
