The problem is resolved in this form:
1 Install BS from scrtch, a clean installation
2 Change the regional settings to English United Kingdon if the version 1 is in english
3 Install the patch 1.01b on the version 1
This is all. When you want play the simulation the regional settings must be changed. Then when you exit the program you can change the regional settings to your cuntry.
This is a little pain but works till the new patch arrives!
