I received my AL539B on Friday the 28th.  Charged it up some via the USB cable and then hooked it up to my 2002 Ford Explorer on Saturday.  Worked fine.  Went back inside to register the product on Autel's website and noticed there was an update to the software available.  I downloaded and updated to the latest software and DTC codes via the Maxi-Link II software.  Now the AL539B will not function properly.  After connecting to the OBD 2 port and clicking ok for diagnostics, I get the progress bar, then it simply lists multiple lines of double digit numbers, such as:

 Replying to my own post simply to provide the outcome / resolution of my issue in the event anyone else runs across this problem.  I traded multiple e-mails with Autel NA customer service with no resolution to the problem.  In fact, they finally quit responding to me.  I then contacted the vendor and requested a return and replacement unit.  The vendor (Motorzone) replied promptly and inquired what happened to the unit.  I explained the problem and lack of fix despite working with Autel NA customer service.  Tina, from Motorzone, instructed me to select the ff 00 00 01 00 09 line, then select the ff 00 00 01 00 68 line, then select any line, then choose default language and the unit should be fine.  I followed those instructions and unit now works fine.
