Google Voice: There was an issue refreshing your inbox? Using Android 2.2.1 (Version.2.3.340.MB810.Verizon.en.US) on a Droid X.  I just updated Google Voice to version 0.4.2.34 yesterday and now I continually get an error message that appears as a notification:

Google Voice
There was an issue refreshing your inbox


Clicking on the notification takes me to Google Voice settings.  I have powered off my phone and turned it back on and the behavior persists.  How do I fix this?
From Al Everett's comment, I decided to try signing out of the application (which gives a warning about deleting all data) and signing back in, figuring that would be a less extreme step than going to manage applications clear data (although maybe it does the same thing). It seems to have fixed the problem
