Hi Peter,
The problem are not the folder rights.
The problem is, that i can not connect to the flynax server.
As i have already written it works with the 4.1 without problems.
I have a file under suspicion, but this is indeed encrypted. (rlNavigator.class.php)
Also this file has changed in the 4.2 version or there are problems on flynax license server.
Regards
Steffen
