Are you sure you do not include the ‘last blank space’ in the paragraph while copying & pasting?
See the tutorial: http://www.avast.com/files/tutorials/insert_key.htm
Please take a look here: http://www.avast.com/eng/i_was_successfully_r.html
Also, check if your system date is set correctly. The license key is valid for 14 months, so if you changed the system date to a value when the key is expired, it becomes invalid. In that case, set the system date correctly and enter the same license key again.
Which avast version are you trying to register (Home or Professional)?
