I’m sorry to hear you’ve run into issues.
The Jetpack plugin does indeed require you to connect to a WordPress.com account to be fully activated.
To do so, you will have to create a WordPress.com account here:
https://en.wordpress.com/signup/?user=1
If you had previously created an account, but forgot the password, you can request a new password by entering your email address here:
https://wordpress.com/wp-login.php?action=lostpassword
Please follow the instructions carefully. You’ll receive an email during the reset process, so make sure you read it for important instructions. If you don’t receive the email right away, check your spam folders as well. The confirmation email can get caught in them sometimes.
Once you’ve created the account, go to the Jetpack menu in your dashboard, and click on Connect.
If you run into issues while connecting, let me know what error message you get!
Please note that WordPress.com accounts are different from the account you use to administrate your blog. WordPress.com and self-hosted blogs available through www.ads-software.com are two different entities.
Please check out the following links to learn the differences.

I hope this helps.
