It looks from the command that two separate ROI files have been input?:
../masks/lAmygdala_roi+tlrc.
../masks/rAmygdala_roi+tlrc

However, the "-in_rois FILE" should be a single file with each ROI defined as a set of voxels with a given integer. Thus, you could combine your data into a 'network' first (assuming each file is a binary mask; otherwise, use 'step(a)+2*step(b)' in the expr):
$ 3dcalc -a ../masks/lAmygdala_roi+tlrc. -b ../masks/rAmygdala_roi+tlrc -expr 'a+2*b' -prefix MY_NETWORK.nii.gz

and then use:
$ 3dNetCorr -inset errts.A0105.tproject+tlrc. -in_rois MY_NETWORK.nii.gz -fish_z -ts_wb+corr -mask mask_anat.A0105+tlrc. -prefix A0105.Amy.corr

(I'm assuming your mask is a whole brain mask)

How does that work?
