DECLARE_ERROR( 
   ERR_OS_FILE_NOT_FOUND                                       , 0x59502);


I have made search by sources
And I see next places

1)  not found our vresources/xml files  ..
  I think this happens on init()


2) Oops,  we throw this error also
When some internal embedded file is not found to be opened


3) void File_Mac::DoOpen()

        err = ::FSpMakeFSRef( pSpec, &fsRef );
        if( err )
            throw xOSFileError( ERR_OS_FILE_NOT_FOUND, get_Name().c_str() );

    if( err )
    {
        if( err == permErr )
        {
            const UChar* pName = get_Name().c_str();
            throw xOSFileError( ERR_OS_FILE_BUSY, pName );
        }
        else
        {
            const UChar* pName = get_Name().c_str();
            throw xOSFileError( ERR_OS_FILE_NOT_FOUND, pName );
        }
    }


I.e. When Valentina ask open some true OS file, but it is not found.
Your client do have db files of course ...


===============
Only these 3 places.

* May be try diagnose db.

* try to move db to other place on HDD  and see if this help

* try to open this db by vstudio may be

* check its permissions just in case ..
