Hello,
If this is in the wrong thread than sorry ladies and gents!
So with this new launcher I've been unable to correctly install a new TP. I've tried different versions and to no avail they don't work. The GUI seems to show up ingame but not the textures. I'm placing the TPs in .technic/tekkitmain/texturepacks folder. I've also restarted the client in hopes that it would work and nothing new.
