Hello!
Please: I would like to update to ---> 3. 0. 14. 276
My version now is ----> 3. 0. 13. 268

Do I need to unintalled, before downloading the last version of Firewall Comodo ?
Also:

¿why in my actual version --->Miscellaneus --> Check for Updates -->There are no updates available? ....when there is now the version --->3. 0. 14. 276 ?

Note: sorry for my bad english.
Thank you!
