What can I do when I see error messages?

This should not happen. If you see them:

• download 'RouteConverter.jar'
• start RouteConverter from the console

Please send me the following information to help me figure out the bug:

• Operating system version
• Java version
• version of RouteConverter
• the file with which the error occured
• the output from the console
• the log file produced by the program

Screenshots and a detailled description how I can reproduce the error are always very helpful.
