Crackshield=Abyss files.
The crackshield has probably nothing to do with the unresponding.
You have to test either if it's Abyss itself or Tiara itself or even the client game that's causing the error.
If Tiara is outdated it can have some problems where certain files can error the game. Try DATA packer to remove all mods then add it back to see if the game still reacts like that.
@ Crackshield: That's what I figured.
Forgive my idiocy, it's been a very long time since using tiara (lol 2009), but is Abyss necessary for CP view? Which is essentially what I'm wanting out of Tiara atm aside from lag reduction. If it's not then I'll focus on just the Tiara hackshield error (see below).
I did re-install on a clean Mabinogi without Abyss and simply got a hackshield error instead. I tried the fix mentioned on the tutorial page for hackshield errors but couldn't find the ESL.clean to rename so that fell out. If there is another method to fixing this that'd be good. I'll rummage through this post for an answer but if the answer to my above question is yes then I'm back to square one on that.
So from what I can tell this is an issue with Tiara. I'll try running data packer to remove everything and try to re-add the newest tiara one more time. I'll likely get one of my friends who is good with mods to TV with me later, but if I can figure it out without bothering him I'd be quite happy and will help me learn for next time.
