Error Codes

Right then as most of you know i have had a few problems getting my VAG-COM to work, i got it working for a second last night and got these error codes,

2 Faults Found:
16486 - Mass Air Flow Sensor (G70): Signal too Low
P0102 - 35-00 - -
18010 - Shareware Version. To Decode all DTCs
P1602 - 35-10 - Please Register/Activate - Intermittent
Readiness: 0010 1101


does anyone know what these are, i am guessing the first one is MAF sensor??

Other thing in the options screen is still not coming up with USB to be able to test it, it just has Com1, Com2 etc any ideas??

Thankyou again,
