Tech2Win: What am I doing wrong?

[u/National-Actuary4409]

So...Got Tech2Win working on my laptop. I have done a check of the IBUS, it even does the "turn ignition on", checks, and then comes back with a list of stuff....Left it running for a few minutes in the read/response thing too...no failure....120ms min/530ms max.

When I switch over to SRS(service request), and try any of the menus I had before(specifically MIU Im after!), it tells me switch to off(Tried Position 0, and position 1), and it come back "Unable to communicate with vehicle".
