Thanks for the feedback on my post, historic_bruno. Sorry for my englishI set out initially did fix version for developers (unstable) .Because after scheduled departures at startup I completely deleted all the data, including repository and dependency and sets the version of the 16 stable. But it does not work (though originally, before the first experiment with a version of 16 virgins all worked fine). Several times I completely delete the entire game version 16 (stable) and reinstalled it according to the rules through the repository, but it does not work the same crash with a segmentation fault).But when I installed after a complete clean version 15 (earlier) then it works. After the upgrade to version 16, it will not start again and does not work.I suspect that this is true and the video card driver is not to blame .. Probably what the files are missing or were within the files or more depending on the very first version of the experiment with the development but I do not know how to find the error and how it can be corrected.
