a couple of troubles

I installed destin basic on a wp site of my localhost to test it.
It looks really a lovely theme and i’m considering the chance to buy a pro version.
however i’ve a couple of troubles:
1. the mainmenu does not works well. i cannot access the second level of the menu. So if i’ve a menu such this:

ITEM 1
ITEM 2
Item 2.1
Item 2.2
ITEM 3

I cannot access Item 2.x because the dropdown menu does not appear.

2. The theme allow to customize sidebar on each page, and menu or category entry. That’s great but a standard sidebar (which runs if there is not a customized) could be usefull.
