Hello, have you a trace error in console ?

If it is not the case you can go in log file that is generated at the start.
Go into you DataBrowser folder installation, then a HOME_IS_UNDEFINED is generated.
Inside you have a logs folder, please send me the log trace that you have.

You can, ovveride the trace level and the folder destination in specifing
a $HOME or %HOME% environment path.
Then modifying the databrowser-logback.xml files root level = DEBUG

There is many reason that your Mambo file is not working, here are the possibilities :
- The database connection is not working (please the Database property)
- The Mambo File have a wrong format (please could you send me your Mambo File and check your files through Mambo)
- The attributes specified in the files are not archived at all ( please check in Mambo that it is not the case)
- You have defined a Sampling option (this part is not working for the moment, the Mysql request is Wrong, I'm waiting for Raphaël Girardot for a correction….)

At the end, you can also try to extract data without MamboVC files. But you need HdbExtractor or TdbExtractor running. I will make an evolve in order to defined the attributes to extract without those devices running.
So in this case, you will have an attribute tree (attribute currently archived or archived) displayed in HDB Tabbed pane or TDB Tabbed pane.
This part, will generated for you a MamboVC files dynamically.
