Open your project in Creator 4.1 (or 4.2), select "Project -> Update Components" and follow the advices.
Yes, I have did that, but thes last versión that apear is 3.20.
I have unistall PSoc Creator, downloaded the last versión an reinstalled. But with a clean installation (PSoc 126.96.36.19910), when I try Project > Uptade Components , at new the last version for SCB is 3.20.
The "start page", load normally news from Cypress, so I asume that there is nothing blocking PSoC Creator to access to the net.
Downloaded components like SCB_v4.0 will be included to a library project available at
[My Documents]\PSoC Creator\4.1\Downloads ( 4.1).cylib
Please open this folder and see if you can find SCB_v_40
I believe to fix this issue you need to recreate the library project.
#1 delete folder "Downloads ( 4.1).cylib"
#2 Open PSoC Creator 4.1
#3 Tools -> Find new components
#4 Search 'SCB'
#5 Select version SCB_v4.00
#6 Click 'Install Checked Components'
