OK Please keep reporting on version 1.52.
In www.reperion.com/newclient there is a version "Reperion for Integrated GPS"
http://www.reperion.com/newclient/Reperion_for_Integrated_GPS.CAB
this should be version 1.0.0.6 (a different, development thread of Reperion)
This version is better capable of handling configurations where the GPS splitter of WM6 is used (which you DO use) (its the GPS icon in settings)
If you can't get 1.52 to work, play with the port settings, set it to the program port selected in the GPS Settings field.
If it still won't work, play (swap hardware& software ports) you can try the 1.0.0.6 version and see how that goes.
The 1.0.0.6 will "freeze" if bluetooth is OFF, and will look frozen until GPS is FIXED.
Anyway, one in 1000 possible configurations will work. Im sure. Our problem is finding the right one.
A community for and by the people, the ideas are endless, enjoy !
