We cannot emphasize enough how important it is that you report bugs!
Unfortunately we do not have enough resources to always ensure that Endrov runs on every computer under every condition. Thus unless you tell us, chance is we never get to fix that bug you're experiencing.
How to file a bug
Go to our Bug tracker. Create a new issue. Fill in your problem.
If it is a crashing bug, usually some very helpful information is printed to the console. To get access to this you however have run Endrov from the command-line. Otherwise the second best option is to check the log file
