Hi Visvaldas,
If you report problems, it is better to use Help… Report a Bug in the menu because it tells us what version you are using, on what platform, etc.

(1) However, it looks like the same issue is already reported as a bug ticket #16322. This ticket is still open (not fixed as far as I know):
<http://plato.cgl.ucsf.edu/trac/chimera/ticket/16322>

I have added you to the recipient list for that ticket. One thing you might try is to put quotes around the entire executable path in the AutoDock Vina interface. That might get it to accept a path with spaces in it.
