About Sandisk Warranty

I just purchased A Sandisk Ultra 32GB Flash Drive. What is the process to register your product. Is it mandatroy to register the product if at all ? I tried creating an account herebut every-time it shows a strange error mentioned below

There was an error with the request and the action could not be completed.

Right now I am stuck , and honestly the whole sandisk website does not look user friendly at all. 

I’m not sure you have to register the drive.

The Return Merchandize form http://kb.sandisk.com/app/answers/detail/a_id/5232/~/return-material-authorization-(rma)-process gives a link to register your product when you wish to return it.  That link leads you to here: http://kb.sandisk.com/app/utils/create_account/redirect/account%252Fprodreg%252Falist  Is that the webpage you tried?
