You can set your GPS Configuration in the file
wigconfig.config
in the directory where player.exe is.
Maybe that helps.
<configuration>
<appSettings>
<add key="AutoDetectGps" value="False" />
<add key="BaudRate" value="4800" />
<add key="Units" value="Metric" />
<add key="CartDirectory" value="\My Documents\Groundspeak\Wherigo\Cartridges" />
<add key="CommPort" value="COM4:" />
</appSettings>
</configuration>
On which device are you working on and how did you manage the .NET-Framework-Installation?
I'm using MioPocket 2.0 R38 and try to install Wherigo-Player on a Magellan Triton 1500.
For now no success because of the Compact Framework-thing.
