I know, I know... It's not a let's play, but I didn't know where to put this so...
I'm starting a Tekkit tutorial in spanish (my native language) so if anyone here speaks it, make sure to check it out .
My YT channel - www.youtube.com/Nehrox1337
I tried pressing F7 but that's just for Matmos. Anyway, I can live without those sounds (Philosopher Stone and the Charge/Discharge of the items). The rest are working perfectly,
I have Java 7 and the sounds isn't working for me either. The thing is that at first the did, but apparently they decided to take a vacation or something like that xD.
That happened to me too. What I did was the next:
Go into your server folder, then in the "Config" folder you'll see "NEIServer.cfg", open in and then in the "item=" section just delete OP and put the username of the people who you want to be able to use it.
I hope it helps :)
