After a clean windows installation and railworks , i was not able to export my created bleuprints anymore.
Big problem for my upcomming talent br643 i was not able to import in in the game anymore.
Do you wanth to do a fresh installation please backup the following file first! you can found this on your railworks root folder.
Since the last update the bleuprint editor is corrupt/not working. if you wanth to export you found some problems that looks like this.
error: The Parameter is Incorrect
If you have this problem please replace your bleuprinteditor.exe file with the old one !
after doing this your export works again.
contact railworks afcourse with this problem
