If you give me your credit card number I can help you with this problem (don't do it - just kidding).
I would NEVER post my personal SN on a public forum.
1. Where did you get the serial number?
2. What product are you trying to activate (be specific, Product Name, release year and 32 or 64 bit version)?
1) I got it by registering as a student, to get a 3 year license.
2) AutoCAD Mechanical 2014 - English; 64 bit OS.
P.s. sorry, if I do not understand something. I am not very good in english.
