I am sorry I opened a new thread abut it : here was my initial post :
"Hello , I am a big fan of Jdownloader. In the years that I use it I have never encountered a single problem until this fateful day
Ok so Yesterday I updated jdownloader (774 updates) and after that I saw that Jdownloader lagged and was really slow or I had to force quit.
After multiple efforts I decided to move the app to the trash ( I am using OSX mountain lion) and re install it . BUT when I try to reinstall it it give me this message :
"Jdownloader is damaged and cant be opened . You should move it to the Trash ""
I tried to Do what reztoki said but it didnt help me much. ( opened the jdupdate.jar and updated the file ) but again I am acomplete noob when it comes to these
Could someone please post step by step what needs to be done in order to fix this. Appreciated !
