Force close when accessing FL from the first screen

Tried it twice, force closed both times. Nexus one, rooted.

delete and re-install seems to fix problems...

Already tried.

Did you try rebooting your device?

Yes. Had it force close just now when trying to join a friend.

1.7.2.1 version is now on the Android Market and PL website, please grab it and see if it fixes things for you.
