Hacking (Smash 4) Can't compile .acm files using FITX v0.77

[SmashRacer]

If somebody could please help me with this problem that would be appreciated.
I have run into a problem using FITX v.0.77. It's when I try to compile fighter.mlist and all the files back it gives me this error:

C:\Users\Name>C:\FITX_v0.77\FITC.exe -be C:\FITX_v0.77\captain_source\fighter.mlist -o C:\FITX_v0.77\output

Unhandled exception: System.ArgumentOutOfRangeException: startIndex can not be greater than the string length.
Parameter name: startIndex

at SALT.Scripting.AnimCMD.ACMDCompiler.CompileFile(String filepath)
at FitCompiler.Program.compile_acmd(String mlist, String output)
at FitCompiler.Program.Main(String[] args)

But when I remove all the acm files from the animcmd folder this happens:

C:\Users\Name>C:\FITX_v0.77\FITC.exe -be C:\FITX_v0.77\captain_source\fighter.mlist -o C:\FITX_v0.77\output

> Finished


Then when I look into the output folder where the files are, all the bin files are only 16 bytes in size. The file size for motion.mtable in the same output folder is the same as the original. I don't know what I'm doing wrong here.

Looking at the stack it seems like when processing your command it hit an error with one of your lines, perhaps check over your edits and make sure that you don't have anything unusual (Seems like it is expecting something in a line but the line isn't long enough to contain something?) if you can't find anything wrong with that make an issue on Sammi's github page for SALT and include all of your .acm files for him to look at and figure out this crash.

@jam1garner Thanks for your answer.
I fiddled around with different lines in the command prompt. I still got the same issue.
I even tried to ask someone on the Smash 4 Modding Discord. He showed me pictures of exactly what he did, the problem is still there.
I also tried to do it on my desktop pc, the problem still exists.
Then I looked on Sammy's github page and there is already an issue posted by someone else with the same problem as me. The issue was posted by the person on September 30 and haven't got a single comment yet.
