I cannot open Google docs in Libreoffice.

http://askubuntu.com – I've just installed isync to use Google Drive on Ubuntu 12.04. Its really nice, synchronizes very well. However, I'm not able to open my doc files using libreoffice. The error is mainly this: The file filename is corrupt and therefore cannot be opened. Libreoffice can try to repair the file. When I click repair, its says read error. Do you have any idea about this? (HowTos)
