Old version of Hijack YES
When I try the Update Hijack/JEmplode it says the JEmplode is up to date then says I have to be connected via Ethernet and have Hijack installed. I have both Ethernet and Hijack as did I before version 42 and I had no problems with 41 I'm not new to JEmplode.
I notice that v41 would say it's checking for Hijack version but v42 doesn't do it at all just goes to the player database.
