Bitcasa gone from right click menu?

I have just upgraded to 10.5.1.0 and now I no longer have bitcasa showing up in the right click menu. It was there with the previous version but now it's gone. Is this a bug or am I no longer going to have access to bitcasa?

It's blocked by default now as it's been causing problems for a lot of people. You can unblock it if you wish, though (just remember that you've done it in case you start seeing crashes, as they may be due to it).

Details here: Shell extensions which are blocked by default

thanks, Leo! I'll cautiously allow bitcasa back into directory opus and see what happens.
