Hy welcome to GC
if you would have used "search" you would have seen that few days ago i had and i solved exactly the same problem
viewtopic.php?f=8&t=4891the solution is in the second message of the link:
that was regarding Samj help, that provided by Rod may have some difference , MEANING THAT THE NAME OF THE FILE(s) TO UNBLOCK MAY BE DIFFERENT, but the principle is the same , so the solution
there are only few files outside the help/en subfolder , just open their propriety and unblock as in the screenshoot on the linked page.
