Hi Stefku,

Thank you for the bug report. The project was compiled with Java language level 1.8.
I've deployed a new version targeting Java 6 so it should work now. Please let me know if it's fine.

Hi Ziolko, thanks for the quick fix. Unfortunately, I get another Exception, but apparently, it's getting closer :)

It seems I was too optimistic when it comes to compatibility with Java 7.
I've fixed the mentioned issue so please try again with the newest version.

Sorry for the inconvenience and feel free to report other bugs and request features. I can't promise anything but I will try to add/fix things from time to time :)

[Stefku]

Ziolko, I had no inconvenience. I'm very glad that people like you have good ideas and also implement them :-)

Anyway, my problem ist solved with version 1.4. Thanks alot.
