But I don't understand as my adwords account is link with analytics.
Google understands your AdWords account has not been properly linked with your Google Analytics account. Without this, we cannot ensure that your AdWords data will continue to populate in your Analytics account.

It sounds to me like a mistake. Someone created a script using a wrong sql query and called it test.pl and ran it (perl test.pl).
Although I don't really have the details on this, I wanted to jump in and confirm that the email is in fact legit. I do apologize for the confusion.
GAnalyticsAdvisor will stop by later in the day and answer your questions about this. To set reasonable expectations, I've seen his calendar and it'll probably be late afternoon.
Thanks in advance for your patience.
The Google Analytics team sent this email as more of a precaution than anything else. We wanted to ensure that users will continue to receive AdWords cost data in their Analytics reports after future system updates.
It is very possible that many users will, in fact, not be affected in any relevant way. However, we wanted to give users an ample warning to double check their accounts, just in case. In the very near future, AdWords data will only appear in a user's Analytics reports if the "Apply Cost Data" box is checked within the AdWords interface.
The Analytics team did meet again to discuss the effectiveness of this email, and do sincerely apologize for the lack of clarity in the original communication. The message did not come across as clearly as it could have.
We have seen a bit of foreshadowing on this. There was a technique with Google Analytics to use a custom filter to show the Adwords Keywords + the real keyword searched. This was an easy solution for online marketers to see the actual keywords searched. This was awesome data for examining the "broadness" of broad match. That functionality was removed early Jan 08. It had something to do with a system upgrade and that GCLID code.
Right now Analytics accounts can be moved (unlinked) upon request by Google from one Adwords account to another. The email notification said that in the near future that function would no longer be available. If the changes go through as the email stated, they will provide more privacy and security for the Analytics users. That could also cause some painful problems for Web design companies and SEMs who just setup Google Analytics profiles under their own accounts.
