1) When you run JDownloader again, do you still get this (around the 22 line in the log)?
Code:
JDClassLoader-> Not loaded due to sig violation: C:\Program Files (x86)\JDownloader\JDownloader.jar
This could be the entire problem, but we have to figure out why this would happen.
Please make sure your log settings are set to ALL (Settings - Basics - General - Logging Level).
2) I noticed that some messages are in Italian, but JD is set to use English (en.loc)
What language is your OS set to use?
What browser are you using and what language is it set to use?
What language does the web site think you are using?
3) Also, from your command window in OSX, please give me the output from
echo $path
and
echo $classpath
(you may have to use the set command to see the correct capitalization for your OS).
In Windows these are %path%, %PATH% and %classpath%
I will upload a batch script later that will collect a lot of information for you to either attach or post on x7.to (used to be bluehost.to). Right now, it will only be a Windows (2000 and later) batch file.
