I have recently bought Full helios along with full Ecto and 5k Toricredits off paypal. I have unpacked all the pieces. I activated all my helios items, yet they refuse to show up while playing in game, please help me out

depends what version of toribash are you using?

I am using the newest version, yet it refuses to show up.

I had this problem too. I never figured it out :P. i just sold mine and it worked for the person i sold it too. I am using version 3.6.
Basically wot i am saying is just sell it. it normally would work for someone else. and u make money!

maybe it takes some time.

re-login
probably reinstall / try playing without shader (if u use them)

Maybe read Support Board Rules.
