FNIS (Index outside bounds of array--issue)

[Awkward Nymph]

This just randomly happened one day, I tried running FNIS and it first gives me this error about a missing skeleton arm, so I move something around and now it's giving me this other annoying error.

I have no idea what I did or am doing wrong.  I may have added one or two mods, but nothing really big.

Try reinstalling FNIS files.

For me, that was happening, until I removed one of the big Poser mods.

I am using FNIS XXL if that makes difference.

I had a hell of a time getting it to work to begin with, but I'll try. I couldn't possibly make it any worse. :/
