MicroStation is crashing when trying to access "Button Assignments" in User Settings.
Try one of the following solutions:
1. Reset MicroStation to default:
2. Restore button seed file:
I. Open configuration variables manager in MicroStation
II. Find the MS_BUTTONMENUSEED variable and open the system folder, to which it points
III. In that folder you'll find a "default.btnmenu" file - replace it with a "default.btnmenu" copied from a PC with a MicroStation installation that does not experience this issue
3. Reset preferences folder:
I. Open Key-In in MicroStation (Home > Primary > Key-In)
II. Type the following in the key-in window:
$ % explorer $(_USTN_HOMEPREFS)
III. This will open preferences folder - close MicroStation and remove the whole folder (together with subfolder), cuting and pasting it to a different location (that will serve as a backup).
IV. Restart MicroStation
