Xhorse Multi Prog Remaining Using Time 0 Solution

Problem:

Xhorse Multi Prog failed to read a Kia MEG17.9.12 ECU.

Error “Failed to load S0. Error code ffff55aa, the number of times used is 0.”

Any idea?

Solution:

Just as multi prog software said, sync device and try again.

Go to Update Online tab-> Authorization management and sync device.
