If you have old .sbb files that you saved prior to the latest (Feb 6th) update then they will no longer work.
If you want to update the files just open them in a text editor add a blank line at the beginning of the file and add a 0 to the line.
The new file format includes a flag to indicate whether you have set the "Ignore Card Count" option. This offsets all of the other data so old files won't read correctly unless you add a new line with a 0 in it.
