I had to force quit JDownloader 2. When I attempted to reopen it, I got the following popup.

I tried the solution offered below but my Jdownloader.jar was still there after deleting the other files. I put it in trash and it was the same result. I didn't empty my trash bin so if it's needed I still have it.

I ran into a problem with downloading the Jdownloader.jar file because when I tried to download it, it's a dmg and not a .jar file.

Any assistance would be greatly appreciated.

Try this:
1. Backup your config (cfg folder).
2. Uninstall JDownloader completely - delete all remains of it.
3. Re-install JDownloader (link).
4. Restore your backup (copy back the old cfg folder).
Check if it's working now.
