PL Auto-crash?

[Zerious]

I was attempting to purchase some platinum, and when I the confirmation notice came up I tapped "buy" and it lagged for like 5 minutes and then I tried tapping it a couple more times. It crashed on me, sending me to home screen. Now every time I try to start PL, it starts the STS animation then home screens me right away. I've tried resetting my phone, uninstalling/closing resetting, and resetting my settings, all to no change in startup behavior. Is there a fix for this?
