[Solved] Exception while extracting certain 7z files

Hi!

I've recently been downloading a bunch of 7z archives and noticed that some display an error message. Below is what the extraction log says about it. Will provide more info if requested.
(Using the most recent version of JDownloader 2.)

Would appreciate a quick fix!
Cheers!

7zip supports multiple compression methods, see Unsupported Method 21
Please install the updated extraction library from here

Thanks for the info, seems to work fine now.
Any reason for why these aren't included in JD2 by default?
