I have a HUGE problem

[kyletheinilater]

so before anyone can help me they will need some background. I have a copy of Factorio From steam. My Older brother moved away and started to play factorio there. I tried to load his world to look around and got this error:

Attempt to remote call outside of an event
stack traceback:
[]__creative-mode__/control.lua:73: in main chunk

What is this error telling me and how do I fix it and How can I avoid getting this error again.

After a bug fix in 0.15.27, the Creative Mode mod is unable to run. Until the author of Creative Mode updates, either turn off Creative Mode mod or revert to 0.15.26.

there is a fix here.
