Problem with OBDLink MX+, EX

Hi All,

I'm new here, searched around and found some tips, but none of them solved my problem.

I've got a newly registered version of Multi ECU Scan. I tried using it with an OBDLink MX+, but MES wouldn't connect to it. After reading posts here it seemed that USB is better than Bluetooth, so I purchased an OBDLink EX, which arrived yesterday. I can't get that to work either.

Focusing on the EX (USB), I run MES and hit F9 to configure. I go to connections, then interfaces and scan interfaces. It correctly finds the EX. When I hit the test button all tests pass, and I get the message "This interface is compatible with ELM 327 1.4! Should connect properly with all CAN modules."

When I hit F10 to connect to the ECU, it fails with the message "ELM327->ECU Connection failed!".

I tried running the OBDWiz software that comes with the OBDLink readers and it works just fine. But MES fails as above.

Any suggestions? What am I doing wrong?
