Tuneup 2015 error with licence

Hi Rajendra
Thanks for the quick reply but at this stage I am confused. I was given a link after the purchase and the downloader copied the program over. See part of my email below :

Hi Guys - Been using Tuneup for quite a while long before AVG days. Recently I got a trial 2015 version from a friend and installed that to try out the program. I uninstalled both my 2014 and 2015 trail and bought the program which the downloader downloaded and installed. Also received the new license number per email and thought I was set !

Here is where my problem kicks in. I cannot activate Tuneup with my new license number. it comes up with "Sorry, you've entered an invalid license"error
Dropbox - Error - Simplify your life

Please help !
