First of all i believe you should use leaprc.ff03
Then if the errors are there regarding definitions, save them in the
atom94.lib using redirectional operator ">".
Now load it again.
Remember that your file doesnt have definitions required for the structure.

I tried modifying the leaprc.ff99SB file to include the new atom hybridizations (ex: { "N3" "n" "sp3" }, see attached) but for some reason when I have it in my home directory it won't load properly, rendering my patch useless.
