This type of error is rather nasty in my experience.
What mod did you install lastly? And can you uninstall it?
Also (please note, it's maybe smarter to fix the above issue first), in your signature you have a list of mod names, I assume you mean those are the mods that you have installed?
In that case, then please replace
MVAM BCMOD formatt (beta) with:
MVAM InfinityWhich is the latest version and adds plugin support for MVAM ships (it comes with the seperating Galaxy and Prometheus, the one which seperates into 3 ships).
Lastly, if you have questions about what to do in the previous thread, feel free to ask.
