No Google map visible in Routeconverter

[javanes]

Routeconverter works fine on with another PC with the same operating system, but not on my laptop.


Windows XP Pro32 bit
Java 1.6.0_23 (32-bit)
Firefox 23.0.1 (standard browser)
Routeconverter 2.11


This is the complete Routeconverter.log
I don't understand why there is NMEA date in the logfile when I started Routeconveter with the Java Console.
Is there remaining something in memory from an earlier attempt?

Edit:
Can't quote the log file.
