Help CWM cant flash any roms

[Pentium Master Race]

My Galaxy i8150 recently got soft bricked, and i was only able to enter recovery and download mode. When i tried to reflash a new rom from CWM, it would abort, showing "cant open blahblahblah.zip (bad)" . Anyone know how to solve this?

Nevermind i managed to solve it using a new SD card. I hope this would help someone!
