Hey @al42and thanks for the fast reply :)

At this website: 3: Proteins - Part I: Basic and Martinize 2 there is a link in the beginning “The files required for this tutorial (including worked files) can be downloaded from [here.]”. I used that link to download the file and the given tutorial for the simulation.

Today i tried the same on another computer and there everything worked fine so it is most likely a software issue? I wanted to try the tutorial on my own computer, which should be possible i guess since it is a small system to simulate?

Thank you very much for help!

My gromacs version (quick and dirty installation):
