Titanium Studio Computing SDK info...

On start of Titanium Studio I have the following erorr:

An internal error occurred during: "Computing SDK Info...".
java.lang.NullPointerException

And then no native SDK can be configured. Configuration just doesn't save!

I already reinstalled the studio and titanium.

I've trying to reinstall titanium and alloy from command line.

npm install titanium -g

But nothing helped. It's on Mac OS X 10.10, on Mac OS X 10.9 everything worked fine. Could anyone help?
