Snapshot restore error - ERROR: Unable to locate table restore file from archive:

I'm trying to migrate the site to a new host.

When I try to restore it at the new host I get the error:

ERROR: Unable to locate table restore file from archive: wp_commentmeta.sql

The zip file does contain that file and the file has data in it. Further, when I instruct snapshot not to restore that table, the same error occurs with the next table.

How can I troubleshoot this problem?

Thanks!
