Witam mam problem z pobraniem najnowszej wersji symulatora ponieważ po około 10min wyskakuje błąd (failed to download the file) wie ktoś może jak się tego pozbyć?

Błąd, który otrzymujesz (timeout reached: 00:00:30) wynika z tego, że przez 30 sekund nie otrzymałeś odpowiedzi od serwera. Po upływie tego limitu czasowego launcher prosto mówiąc poddaje się. W skrócie mówiąc — przerwało ci połączenie internetowe w czasie pobierania.

In the past I sometimes encountered this problem due to slow internet connection...pls check regarding it first. Next check if there is atleast 20gb of free space in 'C' drive. If there is enough space but still the problem continues you can try to download the full game package or part by part package from https://git.ttsk.ngo/td2/td2-game-package and then place extracted parts (if downloded zip file) in C:\ \Documents\TTSK\TrainDriver2. For quick download u can use a file download manager like ndm, idm.

I thought just replacing all the files in documents folder would be enough to update the game but it does not seem to be the case. I think this direct link should work for download of the current version of simulator - https://mirror-2.ttsk.ngo/download/stable/2023.2.1/TrainDriver2.7z (borrowed from another thread). Download can be done in the normal way or with the use of download manager which increases the download speed a little.
When download is finished, extract it to the drive of your choice and then import to the launcher app by locating the TrainDriver2.exe file. (I extracted the downloaded zip file to 'd' drive so .exe file is located there).
After that the game can be started and it should work normally
