I would be skeptical about some of that software on station-drivers. If its not on the official website of that manufacturer theres a good chance its just a modded driver from the manufacturer and theres a good chance the modded driver is older than the driver available from the OEM site. As for the MEI issue, I'm pretty sure there is a backup version in the UEFI. You will need to update the backup MEI as well as the "primary" MEI.
