Which car are you trying to connect it to? Your -06 525xi or -09 335xi?
I'm asking because this reads on the ebay site:
Important: This will work for BMW cars from 1991 to 2006/2007. This will not work on cars built from 03/2007 and newer cars (from when BMW started using D-can for OBD communication)

sorry...2006 525xi

 

make sure your COM port is set correctly and some where I read that their are issues with the programs running on a 64bit platform. You should run it on x86. I have no problem and I run all programs on x86. I do not use the usb connection. I tend to find that certain programs do not run well with usb connections, RS 232/db9 is my preferred connection. You have to troubleshoot it through the port security and device manager and maybe regedit on the software side.
