Error on opening LO.

When I try to open a new document (writer program) appear: Restore Windos. The application “LibreOffice” unexpectedly quit while trying to restore its windows. Do you want to try to restore its windows again?"
I can click on both (Don’t Restore Windows – Restore Windows) but LO seems freezed….
OS: Mac OSX 10.7.5
Language: Portuguese
LO version: unable to see…it’s freezed…

Help please.

Thank you
