I want to download DisGeNET IN CYTOCAPE 2.8.3 and after added plugin .jar, I start download database but unfortunately, an error has occured. Download of database file was canceled. Root error:caused by:java.long.nullpointerexception.

Could you please tell me how can solve this problem

You'll need to contact the author of that plugin.
