Basecamp, Trouble after Update

I did an update to 4.2.1 and tried to import the gdb files from the old version ...
doesn't work. get error "wrong version"

Which gdb file are you trying to import? AllData.gdb or a gdb file that you exported?

If it's the latter, that should work. If not, please attach the file or make it available somewhere so we can investigate.

Importing AllData.gdb is not supposed to work.
