Anyone here have any experience with this?

Some context:
I'm looking into some software that was developed with the autoit package. Autoit allows users to develop code using their scripting language and provides utilities that can wrap that script and the vm required into a binary executable. The script is obfuscated in the binary and isn't actually compiled until the application is run so that makes dissecting it with an editor/ida pro that much more annoying.

I've found a decompiler that should handle the software in question but it is of course having issues. Has anyone here ever dealt with this or something similar? Does anyone want to poke at this problem with me?
