View does not display results when added as a block to a region
Verify which of the blocks you have enabled for the theme you're using. To do so, navigate to admin/structure/block. Somewhere your "block created with views" should be listed there. If it is within "Disabled" (near the bottom), then you need to indicate there in which region (like sidebar 1st, sidebar 2nd  or something similar?) you want that block to be displayed.

From what you seem to experience, it seems that hardly any block is enabled (most seem to be disabled).

PS: just to be sure, try to clear the cache ... it doesn't hurt, but sometimes that is what is required ...
