benz star software error solution

Reason: This firmware is too old, too old firmware cannot work on latest software perfectly. Such as E212,207, 222,205, for these vehicles, better to use the new firmware version MB SD C4 (Item number SP100-D) to test. Because when factory develop the new software, they will add some old car to the new software, and will cancel it for old machine.
