did you install client side or server side?

[Caiyuko]

I downloaded from this link http://adf.ly/2920626/latest. If that's not right can you give me the link to the server side?

[alpharulesirulee]

i cant

[Caiyuko]

Okay?.. I thought you were helping me.

[samsartor]

Sorry I never managed to fix this, I ran out of steam. :(

[Caiyuko]

It's okay but I just want to be clear on this, is it unplayable for servers or did I do something wrong?

[samsartor]

It is pretty much unplayable, sorry. I haven't tried it though, but the problem appears to be universal.

[Caiyuko]

okay it's fine. You still did an awesome job on the mod
