Cannot start new version due to this error, anything I can do to fix it?

FATAL: impossible to update database from version 39 to 40.
Please delete the entire database by deleting the related AS2_DB_*.* database files in the install directory.
After this all your user defined data will be lost.
the only idea is that this is a really old database - about 2008 or 2009?
You could just delete the runtime database before the update, that should help.
