Used to work fine but wont start now, gives error about possibly using wrong version of java but i have installed 1.8 and newer with same results, this is on newest version of linux mint leia, any help would be appreciated...

Which version of WireShare are you using?

I deleted the downloads.dat file and got it to work

That's good news. I had the same message given about a java version, so I just reloaded Wireshare over again and it took away the problem.

Does Ubuntu 18.whatever Ubuntu or clone versions have known WireShare problems? The Zorin version 15.3 Core is a Ubuntu clone, where do you go to get more technical info on the structuring of WireShare files that are critical when security requires hiding them?

Not to my knowledge.

Are you having a problem (what kind of problem) and can you specify the details around this?
Your post is vague re: what your issue or query is.
