Basicaly, my files don't have the right one containing the MCA setup, using 5.1.1.0 Universal for MC 1.7.10. They're either not generating the files or they were magi-deleted? Checking other areas as well.

The pathway used (assets/mca/textures/skins/) does not appear to be there, and I downloaded the .jar file.
Full pathway; C:\Users[Censored; User name]\AppData\Roaming.minecraft\assets
at this point, I have only 4 files available, spelling is accurate.
indexes; objects; skins; virtual;

Note i do have the NetBeans IDE, so if that's usable to edit MCA, then PLEAS SAY SO!

MCA's assets are not placed in .minecraft/assets/. They are contained in the mod's .jar file. Open it with an archiver of your choice.

okay welp... frak. Got a free one? xD
DERP grabs WinRar
ty for the help guys!

*Note: just doubble-checked the files, they haven't appeared. System error on the mod?

I don't really understand what you mean. To change MCA's skins, see the bottom of this page: http://www.radix-shock.com/mca--faq.html
