FSB Pro Start Page shows preview of the strategies located in the Strategy folder.

There is a button at the right side of the page which allows you to set a different folder with strategies to display.

A problem appears when you delete this folder and do not redirect the link. Start Page cannot find the folder any more and crashes.

I already fixed this bug and the solution will be available with the next release.

If it happens to you until then, you can reset the settings by deleting the Settings.json file located in User Files\System folder.
