Sometimes an error appears when a (pre-)Midlife instrument was configured with an older version of software that appears when connecting to a newer software. The error will state it is unable to read back the old configuration settings and informs the user to use the default configuration. This is normal behaviour and an extra security to avoid firmware/software incompatibility problems. Though annoying, it only applies to reading back the configuration from the instrument with a different version than was used to program it. You can use the new software to retrieve and convert your data files without problems. Information about the deployment configuration settings used is available in the converted header file (.hdr).
