Stackreg not aligning images

I’m new to using FIJI and I’m trying to use stackreg to align some black and white images I have of nerves.

I have downloaded stackreg and turboreg as per the website instructions, but when I run stackreg the program just progressively shifts the images to the left. This happens in every type of alignment I try to run on stackreg.

Does anyone have any ways to troubleshoot? Thank you in advanced!

Are you just aligning images in a stack then? Perhaps these tools could work for you in this case: Linear Stack Alignment with SIFT or Register Virtual Stack Slices
