Can not open Opera 7.5 on Samsung Galaxy S

Last post by avith5: I never had a problem with the app, but now, I cant open it. Every time I do it, the screen turns black, and then the phone vibrates (which means that an error have occurred and needs close it), so, I cant access to my saved pages because I dont have my phone rooted and dont have Opera Link.
Any solution? I could uninstall and download it again, but I dont wanna lose my pages and information. :(

My info:
Andoroid 2.2, Samsung Galaxy S, Not rooted, Opera Mini 7.5
