Simply increasing a box size may not alleviate bad contacts in and of itself. 
Plus, you're applying high pressure (10 bar), which is probably just causing the 
box to rapidly collapse in on itself due to void space.

I doubt reinstalling would do any good.  If your installation was severely 
broken, nothing would be working.
