New version 1.4still crashing on startup

I just downloaded the new version 1.4 and am still having trouble with it crashing right after startup. Used to work fine until last update before 1.4, then started crashing right after startup. Tried uninstalling the app & reinstalling on earlier version & it would work 1 or 2 times then crash. Tried same thing on new update, but still crashes right after startup. Iphone 3g 8 gig, 2.4 gig free space, system IOS software version 4.2.1
