i duplicated that error u spoke of. dont take this in wrong, but did u go in to start/programs/sprite backup then choose to restore?
now as far as pocket rar goes, i would dload it anyway
go
here dload it to PC. if u have any troubles or whatever, just PM me. its real easy to use after u use it once.
pocket rar wouldnt fix this issue, i misunderstood what u were saying earlier, but its good to have on ur device
