The developer has been having some problems recently with the app and Facebook changing APIs
What problems are you experiencing? The most common solution to most problems is to restart the iPad and reload friendly. Let me know if this works. I'm in contact with the developer so I will ask him if turning off the iPad does not work for you.
I had the same issue and a reinstall of the app did wonders. It doesn't crash any more on startup but still hangs up sometimes when refreshing at which point I close it out of multitasking.
