Mini Opera is not loading on Sprint phone?

[I'mfeelinlife]

I downloaded and installed this on my Samsung Rant and at first it worked fine, then i exited out of the application. And every since then when ive tried to load the program it does not load....either just the Loading page that never changes or if i send the application to the background and try opening it up again later just a white screen.

Pls help!
Any other good, free, fast mobile browsers? My pre installed Polaris internet on my phone is soooo slow and always comes back with insufficicient memory errors even tho I have ALOT of space , i just got this phone a week ago!
