Build is indeed 224.
Custom mod pack: http://www.technicpack.net/modpack/details/goonies
I'm not 100% sure what folders I set it to install in, but I know I did it wrong. It asked for an install directory, which I set to C:\Users\MercuryFyre\AppData\Roaming\.technic\goon, but then it asked for something outside of .technic, which isn't something I've ever seen an installation ask for, so it had me confused. It wasn't accepting any folders I gave it (The "select" button didn't do anything) until I evidently told it the wrong folder.
Once I got it to accept a folder, being pretty disoriented by it asking for a folder outside of a folder and it not working when I did, I got it to install. It didn't get as far as the Mojang screen, instead just being the dirt texture, so I closed it and hit the red minus button in the bottom right of the modpack's icon in the launcher. At that point the launcher didn't want to close and my hard drive was chugging away so I just kinda left it alone for a while.
Don't feel too bad, I got 99% of my files back because Windows is awesome, but thanks for looking into it :)
