I just installed the java file 

ReperionTrailExplorer.jar

   on my Blackberry 8800 , but when starting the software i get the message "Error starting ReperionTrailExplorer: Module 'ReperionTrailExplorer' has verification error 411 at offset 0d4a"

What went wrong ? Could somebody help me pls ? 

thanks 

I have no experience with Blackberries. But I've googled around a bit and found a lot of topics like this one:

"Have you tried pulling the battery? Usually fixes most problems. If that does not work then delete the application and reinstall."
